#high flow

People misunderstand flow in our reef tanks, and the needs of corals for said flow. Different coral species, and colonies, possess different needs of flow. Primarily the flow is considered in terms of powerhead turnover, although its effects are really localised throughout the aquarium, and it is inevitable that not all areas of a reef tank will receive the same flow. In all reef and fish only tanks, the turnover of the water through the pumps, should be at least ten times the total aquarium (not system) volume per hour. For the average, mixed reef tank, a flow twenty and thirty times the volume per hour is more appropriate, though this oversimplifies the very important matter.
Because it is an inexact matter, I will suggest rules of thumb, for determining how much flow a coral is receiving. Low flow would be enough, for example, to ruffle large, fleshy polyps such as those of Discosoma colonies, and the mantles of Tridacna clams. High flow would cause much swaying in soft, tree- or finger-like morphs of soft corals, such as gorgonians. Moderate flow would produce a pretty, 'dancing' effect on corals with long tentacles, such as torch corals. Despite what people sometimes think, it actually is possible to have too much flow, when stony coral polyps begin hitting their own skeletons, or simply fail to expand normally. Knowing the appropriate location by its exposure to flow, is in fact an intuitive and observational matter, not something helped by any test kits.
But what is flow to a coral? Corals are behaviorally simple, sessile animals, and they rely on their environment to bring them their foods, and remove their secreted wastes. Because corals adapt to local conditions, and this is reflected in their growth forms, the needs of a specific coral may depend more on the circumstances of its life history, or how it has grown, than its precise taxonomic identity. Though no coral is infinitely plastic, and some species are definitely more adjustable than are others. As a rule of thumb, corals such as many Acropora and Montipora species should be sourced as 'frags' to adjust without having already adjusted their growth habit to specific conditions elsewhere.
A constant and unyielding flow, or a combination of high and direct flow, can distress corals, even those favoring or demanding of high flow. It should be remembered that flow is potentially something dangerous to coral, and can tear or otherwise physically damage coral flesh. Therefore, flow should be neither too high nor too low, for even those corals regarded as high or low flow varieties. What is appropriate care may be determined by observing similar coral in aquariums where they are healthy.
The most basic form of flow is the output of standard power filters and power heads, known as constant or laminar flow. This jargon refers to the simple, unidirectional blasts of water flow these pumps produce in the aquarium. In itself this is not the most interesting, exciting, or useful form of flow for corals or their aquarist admirers. Nonetheless, it is possible to make creative flow effects, by positioning laminar pumps thoughtfully in the tank,and this can be achieved with a low budget.
Such an effect is the creation of surge flow, which is when water is moved to and from, in a semi-constant pattern - as in the effects of wave action in the 'surge zone', high on the reef slope. Surge can easily be simulated in the aquarium, by regulating the timing of pumps, positioned at opposite ends of an aquarium. Whereas gyre flow refers to robust, circular motions of circulating water, as are best provided and sustained using a special 'gyre pump', rather than standard powerhead designs.
Turbulent, random, or chaotic flow describes the phenomenon of unstable, unfixed directional flow, that is created when flow from two sources comes together. Creating turbulence using powerheads is much preferable than merely using them to create only laminar flow. It is worth pointing out the existence of so-called 'Japanese style SPS tanks', in which coral colonies considered to demand a regime of high flow, are grown in a 'low' turnover of 'only' around thirty times the tank volume per hour.
In such setups the positioning of ordinary powerheads, which generate laminar flow, is low down near the bottom of the tank. Such a thoughtful positioning of the pumps is chosen, because it optimises the turbulence of the overall water circulation, and somewhat creates a gyre-like effect. The flow is directed so as to travel up the tank walls then along the surface, before circulating through the aquarium. Thus the flow is good, without being as 'high' as it sounds, when it is measured simplistically as turnover per hour.

my favorite type of scene is when all four of them are onstage but two of them are having a conversation for the audience to hear and the other two are silently stagecrafting whatever they want.
bonus: luke playing two characters at once while the other three play ping pong in the background

Queen of the Cosmos
Signs are showing. Constantine dreads what they predict.
The Queen of the Cosmos, Successor of the Tyrant King, Ruler of Galaxies, Embodiment of Space, Keeper of Balance, Siren of Stars, and many more.
She's the most powerful BeingTM by millennia. As far as the information John's gotten has indicated.
The stars are flowing, swimming in smooth currents. The sun dims, cracks of darkness revealing nebulae so beautiful. The moon grins, knowing and mischievous. The horizon is a mixture of greens and purples and blues and yellows.
The Queen of the Cosmos will arrive, and she must be welcomed.
The Queen of the Cosmos shall come, and she must be respected.
The Queen of the Cosmos is near, and the royal family will follow.
John grimaced. A Wrathful Prince with a habit of glassing worlds? A Wandering Princess who played tricks? A Knight with a penchant for punishing dissenters with eternal madness? This wouldn't be easy. Time to tell the Big Guys and Girls.

PERFECTIONISM KILLS CONFIDENCE
When you're a perfectionist, deep down it shows that you are lacking trust that a greater outcome can manifest.
Perfectionist tendencies can look like, doubting your abilities, procrastinating, poor boundaries, overthinking, people pleasing and self criticism.
When you strive to impress, get everything right, overthink, over-plan or compete to be the best— your energy gets completely drained.
The way to reverse perfectionism, is to develop trust in the unknown. Embrace flow, stay in the present moment and accept things as they are now.
Start where you are with what you have. Done is better than perfect.
Stop rushing and trust divine timing.
Stop competing and just exist as you are.
Listen to audio suggestions or empowering affirmations to your reprogram mindset and habits.
Learn to say no and protect your energy.
Embrace your flaws, gifts and talents.
Have confidence in your capabilities. Keep going even if no one is supporting or helping you.
Clap for yourself and be self-validated.
Be ok with disappointing others and making mistakes.

"i was never invited to parties often so, i kind of panicked, was trying so hard to impress him,dolled myself up to the heavens, plucked n shaved n slathered mascara on me, he said "You look pretty,but, is that what ya want?" and boy i was stupefied. he was right."
"- he saw right through me, told me "You know, i like you when youre big and bold, you shine so bright Cappy" hook line and sinker, that was all i needed, for him to tell me that he liked me without all this dumb shit on me, just be me."

It’s still Mermay! Have a merman Perry 🫧
I think of him as either being a full merman, or having to deal with H2O-type shenanigans on top of his regular life. I imagine Doof being ecstatic (and also looking respectfully) when he finds out, and trapping him in more water-based traps than before.

.. However, Boya felt that he still wasn’t a real guqin virtuoso and could not bring to the perfection of guqin performance and use it to freely express his feelings. Knowing about his thoughts, Boya’s teacher brought him on a boat to Island Penglai in the East Sea, leaving him to appreciate the natural view and listen to the sounds of the waves. .. A strange and wonderful feeling emerged, and Boya found myriads of harmonious and melodious music from the nature swirling in his mind. He took out his guqin and began to play, blending the beauty of nature into his music. Boya experienced an unprecedented inner feeling. His teacher told him, “Now you got it. You have mastered the real virtuosity of the instrument by learning from nature.” .. When Boya was playing by the water one day, he told his attendant, “As I’m playing the qin today, the sounds are exceptionally clear. I believe someone is listening. Find that person please.” The attendant quickly brought a woodcutter. Full of enthusiasm, Boya played the musical instrument for him. When Boya played a piece conveying the magnificence of high mountains, the woodcutter exclaimed: “Wonderful! Sounds of towering peaks… magnificent and dignified, like Mount Tai!” Boya then played a piece depicting the vigor of rushing water, the woodcutter responded, “Wonderful! Vast and mighty… like great rivers and boundless oceans!” Overwhelmed with joy, Boya said, “Intimate friend! You are really my intimate friend!” That woodcutter was Zhong Ziqi. —Dr. Lunlun Zhou after Lü Buwei 吕不韦 (300-235 A.D.), excerpt from 'From the Ancient Melody “High Mountains and Flowing Water” to the Development of Guzheng and Artistic Realm of the Harmony Between Heaven and Man', emphasis and small change to Boya's name mine
A note on the translation under the cut:
Those who are familiar with my gifs know that when I include subtitles with the scenes, I prefer to keep many of the original Chinese terms in place of a translated version. This requires more cultural and linguistic study on my part as well as on those's who will get to see the gifs, but it also ensures a more complete picture of the source material, as translation is always also a transformation.
In the same vein, I wanted to try and recapture the clever layering that is taking place in this scene, and that is unfortunately getting lost when you are only drawing from the translated subtitles. I have relied on a handful of references to hopefully respectfully portray the cultural context and literary metaphors. In my opinion is this one of the key scenes of the show, not only in respect to Wenzhou's relationship and the way they lay some of their soft sides bare to each other, but also in regards to their character journeys. It elegantly combines casual landscape watching with an important talk about the future and an underlying dialogue about hopes and dreams, as well as recealls the conflict of their personal circumstances. This scene essentially foreshadows what lies ahead, and I wanted to see if I could portray it somehow in a single gifset.
Due to this goal, I have taken some measure of artistic liberty when retranslating. Specifically, the idioms of zhiyin and zhiji that I have added in the background text as poetic additions are not meant to be taken as an alternative, more literal translation to those same idioms reappearing in the dialogue, but rather a more lyrical transfer of concepts that works complimentary to it. I wanted to offer a poetic version that would also speak to those other layers of the scene, without overshadowing it.
"High mountains and flowing water. Soulmates/zhiyin like that are hard to find," was retranslated to "The beautiful landscapes are vast. The few who understand your music are hard to find."
"The world itself is not important. What's important is meeting your soulmate/zhiji," was retranslated to "The beautiful landscapes are not important. What's important is to meet someone who truly understands you."
All mistakes are my own. Please refer to the list down below for the sources and translations I relied on. Well-meant corrections in case I terribly fucked up in my pursuit of artistic expression are always welcome!
List of references:
"方才成就了一段高山流水的佳话 / It just became a conversation about high mountains and flowing water": Google Translate, The Chinese metaphor of High Mountains, Flowing Water from 'From the Ancient Melody “High Mountains and Flowing Water” to the Development of Guzheng and Artistic Realm of the Harmony Between Heaven and Man' on guzhengmaster
"高山流水,知音难觅 / High mountains and flowing water. Soulmates like that are hard to find": Viki Rakuten ENG subs by the Honorable Team with a small change by me to respectfully keep with the theme; "High mountains and flowing water" as in the original, rather than "Yu Boya and Zhong Ziqi", which was what the Viki team settled on to bridge the cultural gap.
"高山流水,知音难觅 / The beautiful landscapes are vast. The few who understand your music are hard to find": What does 高山流水,知音难觅 mean? on the HiNative forum, The meaning of the term Zhiyin from ‘The Legend of Yu Boya and Zhong Ziqi’ on the Hubei China Archive
"山河不足重,重在遇知己 / The beautiful landscapes are not important. What‘s important is to meet someone who truly understands you": What does 山河不足重,重在遇知己 mean? on the HiNative forum, The meaning of the term Zhiji by @hunxi-guilai
The complete subtitles, with these few noted exceptions, are taken from the ENG TL by Viki Rakuten's Honorable Team.
Please also note that I have left out a significant part of Boya's and Ziqi's tale, as the post was getting too long and I wanted to keep the focus on the main event. But I highly recommend checking out the full version if you haven't already!

Drop the perfectionist attitude.🥀
You don’t have to get it right on the first try. You don’t have to have it all figured out. You don’t have to be afraid of looking stupid. You don’t have to be afraid of failure. You don’t have to be stagnant. Just allow flow.
Life is lessons. It’s not knowing it all. Appreciate the journey and bloom along the way.
