hi all. I have a 200ltr tank with a small centre rear weir with 2 returns, one on each far side of the weir. The tank filters just fine and stays very clean but I’m having a bit of a problem with circulation. I have 2 x Jebao Sine Wave Maker Pump SLW-20 SLW-10 10000LPH and have tried placing them in different places. As I said before the tank if filtering just fine all the corals and fish seem to be happy but I have a bit of doubt at the back of my head if all in placed correct, I am getting a small amount of brown hair algae on both sides of the weir and my rock is placed up against the rear glass. Am I over thinking thing or should I re scape, move powerhead/returns etc. any help would be greatful..(I put the lights on so it can been seen better)

Get yourself a couple of snails. Leave that bit of algae for them as grazing area. You got plenty of waterflow in your tank. Siting at 100 times turnover rate. Kind of too high for some softies.
