100 % water change?

Ya, suggested that. But that's a lot of water to make and store and move. Also suggested fozdown.

Problem is the rock is all old dead rock that will keep leaching, so that would be multiple 100% changes over a few months.

Actually a 100% water change will do very little as the phosphate is bound to other thing in the tank , the good news is phosphates have a limit so it can only leach so long.

I agree lanthum chloride will do it but won't happen over night and the amount you'll need is going to be expensive .

Personally I'd set up a temp frag tank with good water while I dealt with the 300g ,I would get water bak n track as I'm sure if it's truly 3ppm then there's probably other issues as well.

I can assume you've double checked the testers

Nothing seems to help the crap leaking from my rock. Running two different kinds of gfo

Not an option. Only tank available.

It sounds like the live rock has turned into a phosphate sponge of sorts.

What about swapping out the existing live rock with resin/plastic rock , then dosing Foz Down as ongoing maintenance?

The resin/plastic route seems to be working for this aquarist: http://www.reefcentral.com/forums/sh....php?t=2391310
