I had one of those days where I just wanted to do something to the tank. About an hour later the light fixture is in the floor, the powerheads are in a bucket next to the fixture running in vinegar water. It always amazes me how much better the tank looks after I get on one of these kicks. I also put about 3 tsp of aluminum oxide in the hob.because my po4 monitor was telling me its time.
