Phil, I think I didn't explain myself clear enough. U were describing the 'ride it out' approach according to which you dose like crazy, elevate CO2 - and I thought to my self that you were giving your plants the best and therefore they shall suck the NH4 out of the water column which could help sometimes in eliminating the GW. I also thought that if you provide your plants with the best of the best then algae don't stand a chance of survival. But then I was just wondering - if you have this approach and it provides good health to the plants and miserable life to algae - why is it then that u don't use it 24/7 all throughout the year??? I also read in APC that you provide only 24 ppm CO2 so I was wondering if you are switching between 'favorable for plants' and 'most favorable to plants' modes... :-) Am I explaining my self better this time?

I usually use my diatom filter after about a week of GW after I've purposely caused a bloom because the other algae are generally weakened enough by that time to be susceptible to my usual control methods. Sometimes I know what caused the bloom as well, such as a dead fish that I didn't catch or when I've recently caused a major upheaval. Since those are temporary and understandable causes a large water change and a few hours of DE filtering will usually remedy the cause and things can then proceed as normal. Sometimes I'll hit the tank with the DE filter if I've got company coming over and there's an unexpected GW bloom just to make the tank worth looking at. I use the "ride it out" method when the spike occurs when I'm not immediately sure what caused it and/or when there isn't a competiton in the near future.
