i know, this sucks. tank is one year old. nitrates were at 40ppm and phosphates were at .25 than the the hair algae attacked ! added a aquaripure nitrate filter and nitrates have been at zero for 2 months. added a phosphate reactor and they have been at zero also for two months. turbo snails do not seem to survive. not sure why. added 6 scarlet crabs last weekend. used ro water until 1 month ago. switched to ro/di unit. yet the algae seems to thrive. the live rock is from that fish place and was their premium rock. i do not believe a had it fully cycled before it went in. it has been in for 3-4 months. any help ? i am tired of looking at it !
