Curious what everyone thinks if the frag tank should be tied into the display and sump setup or if it should be its own separate system. I see the benefit of it being tied into the system is water volume and all in one system. Only downside I see is that it's an all in one system and if it goes downhill everyting goes downhill. Figure equipment is almost the same for either with exception of a second skimmer. Thinking if separate the water change water can be used from Dr water change to change frag tanks water. Would this go against the whole arguments for separating them?
