Fish's new tank project

[JOSH]

what tank dimensions are you going with?

[Fish]

I'm still waffleing a bit on the dimensions but right now it is 30"x18"x17".
The stand is 36 x 18.

I am considering going a little bit longer on the tank (like 32") but still want to leave a little room for the overflow and drain. I am also trying to decide if 17" tall is going to be enough, or if I should go 18". This darn thing has grown already. I was planning on 30x17x17 but when I got the stand and found it was only an extra inch across, I thought it would be nice to cover it completely from side to side.

Progress is looking good there Chad.

Sorry about creating the moral dilemma on tank sizes.

What kind of flow you planing on running thru the sump?

Haha no problem Paul, I appreciate all your help gearing up for this.
I will either use one of the external pumps as a sump return - in which case I would probably have about 600gph going through the sump.
If I can find a decent submersible pump I might use that instead. Ideally, I would like to do about 300-400gph through the sump.

I've just been doing some number crunching and figure that if I use one external pump on the sump return and one on a closed loop, I would have about 35x turnover in the main tank (which is about right) but the water would be going pretty fast (600gph) through my sump - maybe to the point where it sweeps microbubbles into the display.

If however, I used a mag5 as a sump return, I would have a nice and manageable 280gph through the sump. But that would mean closer to 50x turnover in the main tank (because of the mags extra output and because the Iwaki would then be bolted to the underside of the tank and wouldn't have the same losses it would have as a sump return). I usually shoot for about 30-40x turnover but 50x is a little excessive on a zoo/riccordia tank. So, there's the dilemma.

I don't really want the added expense of buying and running another pump - especially when I've already fgot pretty good flow. I might just move the baffles further apart and raise them up and just go with the 600gph through the sump...


What are people's thoughts on this?

Chad, That is a Coralife skimmer alongside your sump is it not ?...........Dave

well if you decide to use submersable i have a nice brand new quietone 3000, can be used externaly as well, its a 780gph pump
