It will not release the nutrients back into your system it just breaks it down so it can be pulled by the skimmer as dead waste.

I've used chemi-clean in tanks up to 2500 gallons multiple times, and never once has a tank crashed......

No screwing around, 100% recommend chemi-clean; all of the site sponsors carry it, do yourself a favour ( OP ) and save yourself the time; try it out.
