Have a read of this:
Feature Article: Water Flow is More Important for Corals Than Light, Part V — Advanced Aquarist | Aquarist Magazine and Blog

Seems to back up the idea behind the newer 'gyre' style powerheads.

I've just turned my gyre to continuous as a result.

OMG thats a lot of very small words lol....


Seriously tho I must have a proper read of that later Ive only very briefly scanned it. It seems to support the chaos theory of water movement ?that I know you have Graeme as do many others now.


Its interesting to read this as you know ive always said that in line with older thinking the flow should be back and forth,this seems to say different.


Thank you for posting this I think it will be something that if a person hasnt read it,it would benefit them to do so.

What it says is you're better off with a gyre, as when the water gets where we want turbulance (at the surface of a coral), fast moving water will become turbulent.

Small fast jets of water aren't much use.

Most of us turn on power heads for too short a period before turning off again to create a wave pattern. We need longer durations to get the whole body of water moving.

Yes that what I  gleaned from it. Its what annoys me with the Eco Drift and the Jaebao the pulse function is far far too short. With the wave box it had a big PH in a box and it sort of breathed in and out with a massive steady force.
Im just worried still over whether it would fit with my daft tank ive only just barely got enough space if all the measurements are precise,its that tight.
Right now both of mine are on else daytime and pulse at night ,mainly because of the noise.

I guess another thing to try is putting your existing powerheads near the top on one side of the tank, on continuous to create a gyre.

Good idea but any further up and they vortex ,I could silicone something to the top slats but this would restrict power Im thinking. Right now,one is lower by a little than the other with both pointing up ,the surface is well rough. What I imagine im createing is two circles,rather than one ,other thought and I have done it in the past is both in sync ,or not? Up one end as high as possible. Seem to remember that for some reason I wasnt happy with it.

Have a play, and chuck a bit of flake in to see the flow pattern.

Yeah thats a good idea,can use mysis to similar effect I expect,give the fish a workout catching it lol. Oooo coral snow....possibly ?


Yeah time for some fiddling ,thanks for advice  8D

Coral snow kind of turns into a huge cloud quite quickly.  With flake or Mysis or anything that stays in pieces, you'll get longer to observe what's going on before it all gets eaten.
