Curing live rock

Picked up some live rock yesterday and well not exactly live.........it's completely dead....it's been of water for about 5.years.....got a good deal so it's mine now.

So it's getting cured....but if I leave it ro water and do a 100% water change every few days......is there any point running p04x4.as well or is that just a waist as the water change will extract this too???

I'd run a small amount of phosphate remover after about a week to be fair it can't do any harm!
Also I'd get myself a bottle of agent green to completely eradicate the po4 once it's cured and been introduced to the tank for a few days!

Only thing with agent green is I'm thinking it may give a false reading whilst the rock is curing.....???

Going to be in London in June so can pick some up.....Will 100%.ro not just draw it out of the rock anyway????

I mean use the agent green once you add it to the tank and your happy it's cured! That way you will be starting from zero again and it's easier controlled! I wouldn't use it during curing myself!

Agent green can strip calcium out of the water as well so make sure you keep an eye on other levels once you use it! Also I used half doses and found it very effective when I was having issues! Went from 0.64 to 0.2 overnight on a half dose!
