adam, I may be missing something, but why are you returning the fuge to the sump?
Ram Puppy You are correct, I have been bouncing this idea around in my head for awhile. I can elevate the fuge easy enough. I am still worried about micro bubbles in my display tank. The reason I am worried is that the standpipes for the return line has a air hole that draws in air. The return line will then put micro bubbles in the tank. I could always just make a surge device that pulls from the fuge and dumps into the main tank. (I know that the water still goes through a pump that feeds the surge device) I am really not worried about that though, it will kill some anthropods but most copods are small enough to make it through the pump just fine.

Yes the surge device will also make micro bubbles but only for 30 seconds or so every few mins.

What do you guys think, does anyone have a gravity feed sump, how do you drain into the main tank without getting a fair amount of bubbles?


-Next question
What do you guys think about me putting the chiller after the skimmer in the same loop. That would mean that I only have to run two pumps 24/7 not three. I have to use a pressure rated pump for my skimmer. I talked to my chiller manufacture and he said that it is fine if I only run a few hundred gph through it or 1200gph that this would not affect its efficient. The main question is will it hurt the beckett skimmer anyway having this much backpressure after it? ( the skimmer is about 40feet down the side of my house)

Thanks for all the help,
