I ordered my 220 reef ready and 160# of agronite sand. It will be in in 2 weeks. So here is the deal i am selling my 2 125g tanks if anyone is interested. What is the best way to start this new tank? has anyone done this? I have fish and 3 long tentacle anemone and a feather duster and 100# of live rock. Should i use my water? It is tap water i just got my new ro/di system. Should i just use all new water and let it cycle? i plain to buil a new sump as well.
