I just recently discoveredthat my tank has wire alge. I got my phosphate to 0 and my nitrates were at 5 ppm now they are 0. I discovered a lot of detritus in the overflow I removed all of it . Cleaned my return pump . Everything is at 0. My main question is do I need to remove it by hand . Or of I keep the levels constant at 0 will it just die off on its own? Mind you this is a 2.5 gallon pico reef setup. So scrubbing the rocks will not take a lot of time just stress on my corals. I need to re aqua scape anyway because I just do not like the look and am running out of realestate. Any tips or suggestions will be greatly appreciate.
