Flow in SPS Tank

In any tank as long as it's random and indirect and the corals are open and still have flesh, you can't have too much imo.
In my nuvo 10 mixed reef I upgraded the return to a 326gph pump, then realized I needed more flow so added an aqamai kps that I run on the 200l sps mode modified to have no night mode. Based on minimum advertised gph my flow is never below 100x turn over given an actual water volume of 6.5g.

I have a Max Gyre 350. It moves a LOT of water in my 6' 225g, but it is too static and I only use it because I can run it backwards, which I need or the thinner branches corals like Red Dragon will start to grow and lean with the flow. The Wavebox gets into places where it cannot.

Moderate and steady is best
You can totally program it. It actually has a nice interface and it goes backwards very well. I like the Gyre, it is just different and I had to add some other pumps to help it be more dynamic. It moves a lot of water, but it is very static even with the varying speeds.

How about two EcoTech MP40QWD's on each side of my 150 and a pair of TUNZE Nanostream Turbelle 6055's which will be getting installed on the back of the tank for any dead spots.

I was running two gyre 250 on a 120 and also found them to be too static for what I thought optimum flow would be. I would gauge that by looking after dumping in food with reef rounds etc. I have since switched to two Wavs and put each gyre on the sides at the back bottom to just suspend detritus. Like the flow a lot better with the Wav. With the Wav I can create a lot more chaotic and random type flow.

Agree. They move a crazy amount of water and it’s probably just the way you use them. I always used Vortechs in the past and had a hard time liking the sheet of water that the gyres moved vs the chaotic cone of Vortechs.
For me, the most chaotic flow comes from CLs with strong, high velocity pump with eductors and a OM 4 way - this is not practical for smaller tanks under 180 gallons. Then, strong flow pumps like Tunze, Vortech. Last is a gyre flow which moves a lot of water, but it is not all that dynamic for me.
Wavebox is different than all of these moving 100% of the water in the tank all of the time. This is different than using a flow pump on wave mode.

I agree with jda in that a wave box is the best way to move water, just hard for most tank to keep one without looking funny. Also I don't like the gyre pumps, they are a pain to keep clean and the sheet of flow is way to narrow, if the reverse mode worked better than it does I might have kept one in my tank. They are good for long tanks but for me they always need other powerbeads with them or corals start to lean towards the flow on either side.
Would depend on what you want .
Nothing says you have to run them at full power.
My 7ft tank I have 2 maxspect xf 250's and 4 wavs running took along time to get them where I wanted them to keep my sand bed intact but everything loves it(but everything does hit 100% at certain times of the day not just not all at once)
What’s a CL and OM4?
IMO, It depends on what part of Coral reef you’re trying to imitate. Often times, flow is insane on places where abundant SPSs are found.
BUT, the amount of flow varies profoundly by time of day, and can be different day to day.
The question again just to make sure that it’s not linear, and not to the point where the corals start losing skin
Cl - Closed loop with a pump under the tank for flow
Om4 - Ocean motion 4 way valve that goes in the closed loop and has a rotating flow diverter to vary the flow through each pipe in the display.

I have 4 60s on my 190. Sand bottom. I kick them up 100 sometimes in reef Crest usually. They love it. The only thing if your tank is off and they aren't happy the skin peels fast on ones close to the pump. I like the 60s cause of the thick glass. I'd rather have more than not enough.
