I'm replacing my tank. Im using the old stand and sump. I have a bit of an algae issue so I'm going to take this opportunity to clean the rocks rip clean style. I spent 7hrs rinsing 30lbs of new sand. So clouds up in the bucket when agitated.
My question is: should I replace all old water or just some? I know I'll lose a lot with the holding tanks and rinsing rock while cleaning the rock. I'd like to replace most of the old SW with NSW but how do you drip acclimate decent size rocks with corals all over them? How would my corals handle No3 going from 10pmm to 0ppm and Po4 going from .04 to .00.
Now that I'm writing this I realize it's probably best to keep atleast 50% old water to keep the stress on the corals to a minimum and to deter diatoms from popping up in a low nutrient tank.
Any feedback is greatly appreciated.
