DIY Sump and Flow questions

SO I am in process of setting up a 50 Gal Salt Tank. I was going to use a canister but was able to buy a 20 Gal (High) tank for $20 from Petco

Note: I cannot use the 20 gal long, it will not fit under my 50gal (30x18x21)

Anyway, so I have so ideas for the sump set up but I need help with Flow..

How much flow do I need? I still need a return pump and I was thinking of a DIY Overflow using PVC Pipe.. I have seen some designs for that but wanted to post to get everyones opinion.. on what I need to set this up

So I will add two 1" PVC Overflows (tank is not drilled) and then another 1" PVC return with a ~500 gph pump. I have a 20H gal tank for the sump, I am thinking the following:

first section Inlet from DT, maybe with protein skimmer?

Should the bubble wall be just before the return pump? or can I do a bubble wall then an open section for extra water then a short wall before the return pump. Will this work?

What about safeties, a float for Display overflow to stop the pump? what about in the sump? some sort of safety to keep it from overflowing other tan checking for the max line which I have read about..

How would I implement an ATO? I am thinking a simple Sketch for an arduino can work for the basic and then i can add for temp etc if i so desire

THOUGHTS?

You can use a storage tub for your sump, if it will fit.

Ooops. I didn't see where you wrote that you found a 20H.

I would go with a flow rate of 250-400 gph.

Perfect.. @ 250-400 I can use one Overflow tube of 1" PVC.. I can build a secondary of 3/4" for emergency if needed then

So how would you segment the Sump??

OK was at my LFS store today and picked up my skimmer and a Return pump.. Now before I post pictures. 2 weeks ago I bought a HOB Eshopps skimmer from the LFS (They only sell Saltwater stuff), reason for that was I was going to start by using my canister.

Then last weekend we stopped in again and the one guy said that I should upgrade to a sump when I can, then I bought a 20G tank for the sump. I cannot return the HOB Skimmer, it was special order and they have posted, no returns on special orders.. so not a big deal, I will the HOB skimmer on the sump as seen below.

In the pictures I have Dry erase marks on the tank for dividers.. I was doing the bubble trap right after the inlet/skimmer but the guy at the LFS suggested the same on the return pump side. I need one divider on the return side I think for a minimum water depth for the pump..

So where should I have the bubble traps and dividers? Looking for some input on that



My DIY Overflow (Mock up, no strainer yet):

Here's my fuge/sump section. It's a little unconventional but the tests seemed ok! (Eventually! I made the fuge with a leak! But I fixed it)
It's an overhead fuge with a side sump.
(Project ongoing!)

The baffles will determine water height so check what the skimmer needs!
The final baffles before the return is what forces the bubbles to the surface so they don't get drawn into the pump.

Hope this is of some use?

Yes it is a Rio Pump..

I have to ask is yours quiet? I am still a long ways from water and such in my tank

I got my glass yesterday and after seeing more sump designs than I can remember I will have the bubble trap on the side by the inlet.. then a short wall by the return pump

I also have a couple float switches along with a 'ping sensor' I plan on using an Arduino Uno for some of the control. I am thinking ATO, but starting simple and working my way there.

I tested my Overflow which works well and I need to build a second one that is improved (or hoped to be improved) I am surprised my wife is not complaining about the PVC pipe in the family room next to the tank.. LOL
