If you haven't bought a reactor yet your best bet is to use Foz Down. It will easily remove the phosphates and save you a ton of money from GFO and hassle with the reactor. I use it here in my coral grow out system and a lot of my customers use it in their fish and coral holding systems in their stores. It is a safe and easy to use product.
