sump plans for 370g

[dxdx]

Have you considered getting a big tank to convert to a sump? Those two sumps look pretty small for that size tank, and the flow rate you're gonna need for rays and large predators. If your pump fails, is the capacity there to handle the extra water coming into your sump?

On my 300, I have a 75G that is 6ft long. I have it setup like this:
2 filter socks > sponge> overflow drain (like Egon's above, drains to the backyard)> K3 moving bed filter > ceramic rings > submersible heating element > sponge > 2 submersible return pumps. Plenty of space left over if I needed to add something.

I have about 35 gallons of free space in my sump, so if both pumps stopped it will not overflow.

Also, I really think if you go with the filter pad over the drip tray you're going to regret it if they clog and it spills over. If you go this route, at least drill some holes so it will overflow back into the sump.

haha i could imagine that you are filling a seperate tank with water to supply all the other tanks with fresh water... or are you using a ro/di unit?

so i should drill the holes above the drip tray in case of an overflow?
because i can do this

This is the wrinkle, I don't believe in the need to filter perfectly good drinking water before I put it in my fish tanks. I'm not just saying that I did the math and it's just not necessary. IMO. - let the flaming begin

I put 1" holes in the 4 corners of the drip tray and run a 1" PVC through the holes. Have the PVC at just below the top of the sump so if the filter pad clogs up the water level will rise and spill into the PVC and not over the sides of the sump. I can take a quick pic and show you but I'm completely hijacking this thread, I feel like I should send you money

.......i cant do that lol because the drip tray is being held up in the corners by some acrylic blocks... oh haha i could just move the holes so theyre out of the way of the blocks... lol FAIL

yeah, above the drip tray in the piece that separates the two chambers, so if water rises it will spill into the second chamber rather than onto your floor. I'd do this after it's all set up and running so you can see where the normal water level is and go just above that.

...or what Egon said. As long as you have a way for excess water to drain in case of a clog...

that look good for the filter sock sump?

Yeah, just have the holes on the side somewhere so the filter pad isn't covering them. Also you may need to use a type of sponge pad just above the drip tray or some guys use those light diffuser/egg crate stuff between the filter pad and the drip tray. If not using this barrier between the drip tray and the filter pad then the filter gets clogged sooner and kind of gets stuck in the drip trays holes. When you remove the filter pad it has these little black dots where the drip plate holes were and everything else on the filter pad is perfectly clean.
