I would say that is the most popular way of cutting and keeping frags wheather you will be selling them or growing them out.I think most people would love to have a frag tank, me included but when you figure that you need a designated tank, sump, skimmer, heater ,lights etc etc. We say no I think i'll just place a Frag rack in my tank. Infact there is a sweet set up advertised here on TFT for sale, Fantastic tank and light for 3 hundred bucks, what a steal but it's the time to cycle it and where do you put it?
