I have 3 Maxijet 900s in the tank right now, but as I said the adapters takes A LOT of their potential flow away. I do plan on doing a lot of water changes etc.. while I am cooking all the rock, and possibly add some more HoB filtration. Another alternative is to leave the sand in until the day I was re-adding the rock, do you think that would work better then removing it all at once?
I don't know how I have such high nutrients either, I only have 2 fish both about an inch each and feed once daily and none reaches the bottom, it is all eaten. I don't add many extra supplements that would contribute to that either. I got my RO/DI system about 7 months ago, but it hasn't made much of a difference.
