So getting some GFO might not be a bad idea going forward.

Thats the ticket. You might have to deal with the extra iron in your tank wayne and run gfo intermittently.

Yep, I may just have too. After reading more on Zeozym I am thinking that it could be breaking down the proteins in the rocks thus resulting in this sudden po4 spike. Just did another 20 gallon water change. Tested the water before the change... Still at .21. Will be testing the water tomorrow and hope that it has dropped... Will be preparing another batch of water in the morning. So far no casualties ( knock on wood )...

Does running GFO tend to increase the iron readings in the tank? I know you can get test kits for iron but I've never tried one.
