Remote sand bed ?

I've been running bb for a few months and have added a remote sand bed into my system last weekend. I split one a drain into this sump and feed it back into the main sump for return into my tank. Here's a couple pics.

Anyways, I'm wondering how deep should it be - I added 20lbs bag and have one more, should I add that in too? I think a dsb would be better.

Let me know what you think. Sean.
 
I say add another bag, I did the same thing with my bb and wish I had gotten 2 bags...

Newbie question what is bb?

Bare Bottom => No sandbed in main display tank
 
kpk - Yeah, I think that's a good idea. Might as well make it deeper. How is yours setup btw? I'm having a problem finding the right setting for my pump feeding back into the main sump. I always have to tinker with it now.

Eric Boerner - six inches huh? Good to know, guess I better throw in the other bag!

I'd like to be able and set this once only. It's either too much flow (feeding more back into my main sump, emptying the return on my rsb sump) or not enough (feeding less back into my main sump causing that to drop) and in either scenario its pump air.

Maybe I should just close off the drain and pump from main sump to rsb sump and back. Using only pumps????

Any other help on how your remote sand beds are setup is appreciated.

I think it's nearly impossible to balance the output of two pumps and keep it that way. Most split-sump (or split sump/fuge) setups I have seen have one of the sump/fuges gravity feeding into the second, and the second one has the return pump into the tank.
 
larryl - That's what I'm afraid of is happening with the drain rate. It's turning out to be impossible to match the drain rate with the return rate running off a seperate split sump...so i'm finding out.

If my overflows are gravity fed to sump 1, how can I get it in sump 2 for return...unless sump 1 is physically higher then sump 2? Right? Any pics of these type of setups would help a lot.

Thanks! Sean.

If you don't have a lot of vertical space I think all you'd need to do is put the first one up on wood blocks or something so it's a few inches higher than the second, then drill the side of the first for a couple bulkheads with strainers, which elbow down to drain into the second (use two in case one gets clogged). You can feed all of your overflow into the first, or tee the overflow so some goes into the first and some into the second, or feed all the overflow to the second with a pump sending some of it into the first. Basically the first one is always running full so that it is always overflowing into the second and the level in it stays constant no matter how much or little you are putting into it. Hope that makes sense...

larryl - Yep makes complete sense now. So I'm going to leave half of one drain split and raise the rsb sump to gravity drain into the first main filtration sump. This I should've thought of. Thanks!
