Ok, so I sold the 40 and the 75 in BC, and bought a 90 out here in Saskatchewan. So, I'm thinking I will do a small 2-way closed loop on this tank for three reasons:

~ So I can hopefully eliminate most if not all powerheads.

~ T the pump outlet for an easy water change system like superduperwesman did in his nano contest tank. It won't work in the sump because there will only be about 3-5 gallons of water in with the pump. Will a ball valve seal well enough to have no leaks on the bare end when not doing a water change?

~ To get random flow/waves. So I can get away with probably just using one VorTech (later on down the road when I feel rich again) and not have to use two to get a wave action, or maybe I will be happy just using a couple Koralia 4's or some such thing.

So...any input on how many gph I should run my closed loop? Remember I keep LPS only, although I will add a few SPS to the 90 (I think). Pump recommendations? The OM 2-way wants to use a bypass unit if more than 1000 gph is going through it, which from my understanding pretty much defeats the purpose of using a pump with more than 1000 gph. Or should I use a SCWD which will deplete the gph by about 30%?
