Micro bubbles

Hey all!

:wavehand:

I have a little issue with micro bubbles.. I have always had it but I wanna try to stop it. I have a have a 265 gallon, and a 75 gallon connected to a 75ish gallon sump that probably hold 30-40 gallons when the system is running. It is all connected with a reeflo dart pump.

I have never had the pump on full flow because the more I open the ball valves the more bubbles come into the 2 display tanks. I currently started using a filter sock for my return but that did not really change anything. I was wondering if I should be able to open the return pump up all the way for full flow? With out have micro bubbles? I have to try to find a picture of the sump when I made it, but it is made like any other sump with the bubble traps and everything.

I was think about maybe buying a smaller return pump but when I was building the system I thought the theory was to have about 10-15x the total volume. Do you guys think this is to much flow? I read somewhere that someone thought that 5x the display tank was enough for a return pump.If I by another pump I was thinking about using the reeflo as another pump for the display tank. I really would love to open it up all the way to have more flow in the tanks with out having to buy another pump.

What you guys?
 
Your problem probably stems from having too much flow thru your sump. If you can slow the flow thru your sump, it should resolve your microbubble problem, slow your pump or downgrade
 
Thats what I thought....

What do you think flow thru the sump should be roughly?

What do you think about hooking up a SCWD Wavemaker to my existing dart and using it just as closed loop? I have it I figure I should use it...
 
SCWD's are good as a temporary thing, but eventually calcium builds up, and clogs stop it from switching. I'd look at diff options.

And if I remember correctly the flow thru a sump should be 3-5x its volume
