I've been struggling with green water for several days now. I have drastically reduced the light, do 60% water changes daily and ordered a HOT Magnum filter. Yesterday I got the HOT Magnum put in the micron filter and let it run without turning off the other filter. I have a 75 gal Jetstream with wet/dry filter (with the giant BioWheel). This morning after the HOT had been running for 18 hours there was little or no difference in the algae. I then took the HOT off and opened it up to check on it. There is some algae on the filter but it isn't coated and clogged or anything. So, I put it back on the tank and turned it on and turned off the "main" filter. Should I have turned off the main filter when I put on the HOT Magnum yesterday? Shouldn't the HOT be having a bigger, quicker impact on this tiny green algae? Should I let the HOT run with the micron insert for days at a time?
