Tank and sump turnover rate
 

I was just wondering how many times everyone has for tank and sump turnover rates. I have a 6ft 300 gal. I'm running about 1000 gal per hour through my sump and with powerheads about 13000gph in the display tank which is approx 43 times total turn over. Im just wondering if I should increase the flow to my sump. Or stick with what I'm running. This is the first time I've ever run such a small amount through a sump and the biggest system I've owned. I think the water is not as clear as it could be and I'm just wondering if that could help.

With head loss I push about 1400 through my sump on my 180 gallon. I felt that was on the lower end.

I pushed about 800gph in my 180. I felt that was fine. My current 115g runs about 350gph, again, fine.
I like a longer dwell time for skimmer, carbon and heaters. Keeps noise near 0 and tank is crystal clear.

I put 2500 GPH through my 400 and think its almost overkill. Biologically, I think your turnover should be fine.
If your tank is newish, give it a few months and see if it clears up, if not then maybe reconsider the idea of more sump turnover...

Just use a filter sock.

I'm same as brad. Slower sump turn over for longer dwell time and more flow from power heads to keep detritus suspended

I can't see a benefit to faster turnover rate through a sump, if anyone has one please post it:)

And then put a fat ball of filter floss in the sock , it's a beautiful thing :)

Usually, water being less clear has more to do with too much flow than too little. I think you're fine anywhere in the 3-8x turnover. You're on the low end, but I doubt that's what's causing the water problem. Is the problem particulates in the water, microbubbles in the water, or color in the water? For particulates, I would also suggest you add a filter sock. You don't have to have it going all the time. I just add it for 12 hours after doing my weekly water change. Zeovit's Coral Snow I find is also really good at clearing up particulates from the water when used regularly. Carbon is good for color in the water, and you have to look at plumbing for microbubbles.

I've been running two 7" filter socks since day one. I'll have to give the filter floss a go. Good call Denny. Should make the socks last longer too. I get 2 to 3 days out of the two.
