Re: need algae advise......again
If you have actinic supplemental lighting , run only it for around a week to 10 days and make a couple of water changes in that period of time (especially one just before the end of that period). Actic light wave length does not support the growth of cyano algae. The cyano will die with just actinic lighting but everything else will do just fine. Unless your replacement water is high in silicaites and nutrients both the cyano problem should go away after week without the light it needs and the removal of the nutrients and silicates should prevent it from growing again once you resume normal lighting. People use to put quartz rocks in their tanks and not be able to figureout why they had cyano algae. Pure quartz rock is pure silica. Duh!
