Hi all. The name is Cristian(Cris),and I'm currently running a 650 liters system. Battling phosphates since start. I've started with dry rock this time,treated it with acid,chlorine but not actually used the "cooking" method. Tried GFO,lanthanum,wc,chaeto,nothing worked,so I thought I should give the ATS a try and see how things go...I'm tired of waiting...been waiting for the last 7 months... Well,that's about it. Glad to be here.
