Greg: Mostly, we're just tired of it, but our plumbing is such a tight fit that I think we'd have to re-do a lot of it to fit a check valve. That's why we made sure that our sump can accommodate the drainage from a power outage. Our tank is back drilled with the drains at the top of the tank so only a couple of inches drain out of the DT when the pumps are turned off. Only about an inch drains out of the RBTA tank with the HOB overflow box. Our sump is a 75 gal tank so we've got the room. Our garage is a 1 car and neither one of our cars would fit (I have an Envoy, Tommy has a 4-door Z-71) but it's full of a pool table, still, grrrrr, and, ironically, tank stuff that we haven't installed yet.
Al: Thanks! We've been working really hard on this big project even though it looks like we're moving really slow. Part of it is money the other part is time. Tommy just moved to working 4-10's so he's got 3 day weekends and we've got one day a week dedicated to working on the tank until we get it established and the rest of the weekend to do other stuff.
JoJo: I REALLY want an RBTA (rose bubble tip anemone) but I want a tank dedicated to it. I don't want to have to deal with worrying if it wanders over expensive or large corals so we plumbed the 41 gallon into the larger system for the stability of the larger water volume. I may stick some small zoas in there once it seems like it's settled. We're not going to be able to add it right away of course, but the fact that we're working up to it makes me really excited.
