Anderson - a valve on the output of the pump can be partially closed, this will reduce the flow of the pump, but also reduce the amount of electricity used by the pump.
It is what I would do if I were planning for a large system, but starting smaller.
Ed -
I hear you there, trying to redo everything you have or install an expensive heating system isn't worth it to save a couple hundred a month in electric. If you ever build a new facility though, or for some reason are doing a large remodel, just something to consider. The guys that run the coldwater tanks all insulate their tanks, and they recommend acrylic over glass also. I suppose that's another possible consideration for acrylic. What about styrofoam sheeting.. could you slide that in along the backs of the tanks?
As far as the fish go - I reckon you really only need enough turnover to try and keep the waste out of the tank and in the sump.
Living in Fla, I have the reverse problem. The pump that runs my 210 actually keeps the tank water about 3 degrees higher than room temp. Condensation is not such a big deal down here.. but electricity is expensive.
I don't even have a heater on the 210.
In looking at a broodstock system, I'm not sure that I would even need heaters, probably the pump would be enough - like Ed does - except if I put in a 7a pump, I'd need a damn chiller.hehe You guys will all probably laugh at me, but we keep the heat at 76 in the house, and the A/C at about 78. So life would be a little easier for me in that regard.. unless the A/C went down in the summer, in which case the house easily shoots up to mid 80's in no time.
