Water turn over in sump

[jbtbusiness]

I'm trying to find a good return pump from my sump back to display. My tank is about 70 gallons 29.5w X 24L X 22H

Also how much tank turn over per hour is best, I have heard 5 - 10 times per hour. I appreciate suggestions...thank you.

You will get mixed answers with this question, there is no truly correct answer. Most like me belive in a slower rate thru sump 500gph while others will say get as much going thru it as you can. I will say this , if your sump is small with no bubble traps then keep flow low even if you do have traps in a small sump with a lot of flow will still have issues.

Well said i myself like high flow Not white water or bubbles in DT but as much as my system/sump can handle.

Thanks for the info...Your right I found that answers do vary on this. I do have bubble traps and did have some issues in my tank so I slowed flow to approx 500 gph (about 7 times turnover per hour) and everything is finally flowing the way I want. Water cleared up and bubbles are gone.

It all really depends on what you want. Its good you got it working and set up that way!

Go for the water blaster 3000. I really like it. 3-5x an hour is enough.

I have always stuck around 5x turnover. It gives your skimmer a chance to skim more water that passes through. Also most refugiums (if one is set up) do better with a lower flow across them.
