Bump: Wow... I kind of backed off because the explosion of Algae happened with Ferts with the old light, but you think it might be the reverse problem now?
Yes and no. Just 1 part of multiple parts with our tanks. I've had the same problem as you.
Things were doing well, all of a sudden hair algae here and there. I was constantly removing hair algae with a skewer or with some tweezers and was dosing Metricide (glutaraldehyde). Everything was held somewhat at bay but algae was still increasing. Started to up my water changes and vacuuming up mulm that was on top of my substrate. Realized I was just fertilizing like mad still. Started to read threads and journals here on the forum. Realized the amount of fertilizer I was putting in would accumulate over time. Thus leading to more problems.
So the things I did was:
Dialed my lights back( I have the same light as you) down to 75% max.
Dialed in my CO2 ~30PPM
Dialed in my ferts
Stopped using Metricide started to use H2o2
Twice weekly (minimum 50%) water change with aged water.
Reduced fish feedings to every other day sometimes just twice a week(heavier feeding)
So you must think, wow that's the answer? Nope I still had hair algae. I continued this for weeks. And it gradually got better. Then I pulled out some plants and I started to get staghorn algae.
. But I kept at it. It's probably been a month(at least a good several weeks). Staghorn is starting to dwindle, and so is the green algae that covers my rocks.
Point being, stick to a plan and follow through. It won't change over night. Nor will it change within a week(I've seen some hobbyists that it actually has changed for them in a short period of time).
