I Have triend black outs , UV, silica and po4, copepods, phyto. It comes back next day.
This time I Installed my small UV. I gently brushed any large patches of the algae on the rocks and sand (amphidinium). Turned out the lights for 48 hour.
I do small daily waterchanges (20 gallon tank 1/2 gallon a day) with the new water having massive ammounts of po4 and silica added.
I set my led lights to slowly ramp up from 0 percent to 80 percent over a total of twenty days with the theory that this will hopefully allow better competition of desirable surface algae.
We are about a week in and so far so good. I hope I didn't speak to soon but I think this is doing the trick.
