Hi evryone. In my planted 150 gln discus tank I have a very bad algea problem I was adding nitrate in my pmdd and it went up to about 60ppm and the algea went crazy!! I got the nitrates down and do many water changes but the algea wont leave!! Now some white stringy fuzz is growing on top of the algea!! What is this??? Please help!! Bobby Brunner at aecom_yu.edu
