Sump help

[gregzz4]

The only drawback I see is it will put your skimmer farthest from the cabinet opening, which is not ideal for servicing

The trapezoid will end up against the wall, Ya ?

I am thinking I have two options and that is one of them and the easiest. I have some lexan I could silicone in and would be done.

The other is to have the skimmer in bottom left and return pump in the upper left. Throw in a bubble trap. Have the fuge in the right trapazoid and build a wall there as well to give me some volume and have water fall over it and then under into the top left return.

So just have returns going to both skimmer and fuge chamber and use ball valves to control flow.

Trapazoid is against the back part of cabinet so skimmer would be far away...

It would be better longterm if you used glass, not lexan, unless the area you place it in will stop it from moving - angled to fit with pressure holding it in place. Plex and glass don't silicone together well. Many have had success siliconing plex baffles in sumps, so you may be OK, but I'd use glass

OK, so your plan would be to increase the wall height and have the lower left skimmer area(drain from tank) go through a bubble trap, then spill into the trapezoid (fuge) and go under the glass to the return chamber ?

Sounds much more complicated

Ya, I hear ya

I'm thinking ...

OK, for ease of access to the skimmer and return pump, but not much access to the fuge, this may work

Think of your sump the way you will see it when the tank is against the wall/in the corner, with the longest edge against you

Have the DT drain into the skimmer chamber on the front left
It flows under the baffle to the fuge, then spills over to the right front chamber where your return pump would be

You will need to raise the tops of the glass to make this work, but it will become a bubble trap, and no worries about sand migration (if your skimmer is on a stand)

The glass between the skimmer/fuge and skimmer/return would need to be taller. Simple strips will do

[gregzz4]

If you go with this latest plan, you'll still need a sand trap
On the inside of the fuge past the underpass. Maybe an 'L' shape to the center baffle between the skimmer and pump, or even just a simple strip on an angle between the baffle and the far left wall

Another option is to scrap the 'fuge altogether. It would simplify your sump. That is unless you're dead set on having a 'fuge. Just throwing that out there.

I thought the same thing, and also wonder about socks, but the OP wanted some options ...

Nothing wrong with the setup, just kinda hard to work with

[smokinreefer]

okay, if i got the orientation of your sump correct.
this should work.
if section 1 is at the back of the tank
section 2 is front left side
section 3 is front right side

tank drains into 1
flows under baffle into 2 (refugium)
over baffle into 3 (return pump and skimmer)

you'd need another baffle in section 2 just behind the current baffle.
(colored in red)

this baffle would go from the bottom of tank, and would be shorter than baffle leading to section 3

this way, water flowes under baffle 1 (bubble trap)
flows up over new baffle (into refugium)
and then over 3rd baffle into return chamber!

make sense?!?
