I recently posted about the green algae problem I have in 2 of my tanks..There were a lot of suggestions and I tried those that were applicable to my situation..One of them was to but some Bristlenoses. I did buy them (2 in each tank) and I never see them out..They have been in there about a week now. I know Plecos are famous for hiding but I did not thinks BN were. Alas I still have the Green Algae...I clean it off (and some of it requires some work) and it seems to reappear. There is no direct sunlight on the tank and water readings are good (amm-0 Nitrite-0 Nitrate-5) I tried a blackout on one of the tanks but it didn't work...Does any one have a solution other than draining the tank and letting it die..I have enough room for transfering fish to other tank but would perfer not to go through such an effort..
