phosphate leaching from rock and sand when does it end?

[Randy Holmes-Farley Verified Community Expert]

just listened to a reef therapy podcast on the way to work today where the guest said he had a client with a tank in the 1.0 po4 range. he ended up dosing a ton of live phyto let it circulate for a few hours then had the skimmer remove it. he said the po4 dropped to normal that day.

Sounds sketchy to me.

Maybe. I haven't looked into it. It was on a reef therapy episode from last October with a microbiologist guest. Thought it was interesting.
