Algae outbreak

[behzad_cooi]

I have a 4 months old 240 l tank. I have 4 turbo snails and 3 tangs including Blue tang, Desjardeni and powder blue. I had some hope these fishes solve my macro algae problem. but it seems that they do not like algaes in my tank. light is Radeon xrw30 G2. parameters: NO3 and Phosphate 0 (not detectable by Salifert test) Salinity 0.026. Ca 520 Mg 1500. What should I do to get rid of these algae?

Looks like a fairly new tank, so just the ugly phase kicking in. Do you have a good CUC? You can remove the rocks one at a time and manually remove and scrub them, then put back in tank and move on to the next one. Or you can just let it be and it will go thru many stages of the “uglies”. But a good CUC and a healthy population of copepods will go a long way in keeping things down.
