SUMP idea (36x14x16)

[MuscleFish]

Hi,

Can somebody check my SUMP idea?

It's good? Can I make it even better?

Any need to improve the mechanical filtration?

Thanks

If you want mechanical filtration, filter socks are easier to replace (and clean & reuse.)

What kind of overflow will you be using? Bean/Herbie overflows don't do so well with tees. It's usually recommended to tee off the return plumbing to supply the fuge.

Also, make sure your sump has extra capacity to handle any water that back siphons from your display when the power is cut.

Can I use baffles for filter floss? 1 inch for baffles is OK (for each)?

Overflow will be Herbie.

How exactly I can tee off the return plumbing? Do I need to change the design from SKIMMER/RETURN/FUGE to SKIMMER/FUGE/RETURN?

Thanks

Can somebody check my new plan?

This sump can take 8.8G water from the tank. Its OK for 107G tank (60x23x18)?

Thanks

1 gallon = 231 cubic inches, so assuming your tank is 23" deep, it holds approx 4.7 gallons per inch of depth. 8.8 gallons would be just over 1.75" of water depth. You should be ok, but you have to make sure there's a siphon break less than 1.75" under the surface.

Look at filter socks if you want mechanical filtration. Teeing off the return like you have shown is generally the preferred means. You can have the order either way. The way you have shown lets you control the flow to the fuge, but saps some of your return flow.

My tank is 18 deep and 23 wide

I redone the buffles between skimmer and return section for better waterline control for skimmer.
If it was you, what to you change in my SUMP?

Do you think 1.5 inch plumbing is OK?
1.5 inch = 1300GPH via gravity.
Jebao DCT 8000 pump (at 4.5 feet (36 inch stand and 18 tank) it must provide arround 1300GPH). But I need some flow for the fuge (how much?).

Or I can use 1 plumbing? Or 1.5 with the stronger pump (DCT 12000)?

Thank you for helping me!

ok - that makes 5.9 gallons per inch of depth.

Quick calculation of your sump plans show just over 10 gallons of headroom, meaning you could drain 1.8" without it overflowing.

I would probably have the return chamber a bit bigger; the total volume of the return chamber determines how long before your system runs dry if your ATO fails or runs out. Right now you only have 5 gallons in there total, ignoring any water depth the pump needs to operate.

10" might be a bit small for the skimmer, maybe not. It depends on the skimmer.

1.5" will be plenty big enough for the overflow plumbing. Depending on the drop you could probably get by with 1"

I'd probably upsize the return to 1.25" plumbing. You can calculate the head loss for your return plumbing here, then see how much flow you'll get from the pump.

Make sure you have plenty of flow through your fuge - if it goes too slow, detritus settles out and just makes it a garbage dump.

How bigger? 12 inches (I can take 2 inches from the fuge)?

OK. I'll use 1' and 1.25 for return.

300GPH is OK or more? It won't create a sandstorm?

My buffles between fuge and return are OK? Or I can use only any buffle with egg-crate?

Thanks!

My final design is like that.

It's good?
