THANKS for the help, I have another question, if I wanna use base rock and live rock, what would be the ratio of live rock to base rock i would need so my base rock would become live rock and, im planning on doing some aquascaping does it matter if my live rock dries out so i can attach to the PVC? Also im wanting to have a bunch of corals and a wide variety of them, would something like a calcium reactor be something that i should consider investing in? Tank is 50gallons and i apologize for all of the questions, i just realize the investment im about to make and want to do it right the first time. Thanks again for the help-Tyler-
