How much flow for a 40 breeder?

[mnestroy]

I have a 40 Breeder with a 20L sump.

I have a:
Ehiem 1250 (317 GPH)
Tunze Nanostream 6025 (660 GPH)

Total: 24x Turnover

What is the ideal flow?

The reason I ask is because I've tried aiming my nanostream to all sorts of directions but I keep having particals blown around. This problem has drove me nuts since my tank has been up 1.5yrs.

Today while cleaning my powerhead I left just my return pump on, and withen 2hrs my tank looked great!

I know everyone says more flow is better! But my tank is houses mostly zoos and one huge LTA (which is on opposite side of tank)

So my question is what is the best conditions? I've tried filter socks, etc and no mater what crap just floats around my tank. I've also tried increasing the flow by adding a Nanostream 6045 (1189GPH) which brought my total turn over to 2167GPH (54x)

Is my 6025 to strong for my tank?
Would the return pump be enough turnover for my tank?

Thanks!

I'd go more...i've got a seio 620 (620gph), an MJ that does like 240 i think...so 860, then i've got my return pump which is sposed to do like 600 but it feels like 200 or so...so around 1000gph total is what i've got...i'm gonna be taking out the seio and putting in 2 hydor koralia 2's, so those alone will be over what i got now, and i'm keeping the other stuff (maybe not the return pump) and i may be putting on a HOB filter. All i've got is softies/lps and a couple sps...been going a year but i think its now time to add more flow for more sps corals

Why more flow, I already have to many particals floating around my tank. I dont plan on SPS

I have 2 Nanostream 6025's in my 40g, no problems what so ever. Do you think your particulate problem is detritus?

do you have a skimmer? It should be taking all of the junk out of your water. You dont want all of that garbage just settling in your tank.

I agree ^^^. My 40g is a sumpless system, so one would think I might run into particulate problems. But, if you keep the detritus suspended in the water column, with enough flow, this will allow the skimmer to get rid of it.

Exactly Step one is suspending the particulate or detritus. Step two is removing via the skimmer. good luck.

I have 31x turnover in my 40B. Comes from 4 different PH's. I'm going to ditch 3/4 and get 2 Hydor Koralia 3's and a Hydor Koralia 1 for across the back
