SUMP HELP

[ngbski_]

LOOKING TO BUILD MY OWN SUMP .. okay look I’ll take any help (online tips/hands on in the Los Angeles area lol) but essentially under my 40 gallon breeder I want to have a 10 gallon sump, NO HOLES DRILLED, more so was thinking 2 pvc pipes running out the back of my tank and into each side of the sump, 1 pulling water, and 1 returning. My questions are. 1.) How will I get water to be pulled continuously from the main tank? 2.) How would I get water to return to the tank at a consistent flow? & 3.) How would I prevent ANY type of flooding to the main or sump? Thank Bros & Brokishas

First, your tank looks very nice, do you *need* a sump?

You prevent flooding by having at least two and even three drains. This article has more on the three most popular drain systems (though I do not suggest using a single drain "Durso"):

Drilling a tank is not hard if you want to try. But, you can get a reliable Hang On Back overflow, like those from Eshopps that do not require drilling.

You want you sump to be large enough to handle all the water that drains back into it when the power goes off for any reason. You might be alright with a ten gallon, but I'd go for a 20 gallon long sump, I think you'll appreciate the extra room.

If you want to DIY a sump, I think the best value going are the baffle kits from Modular Marine on eBay. I think they are a better deal than Jax Racks and Fijicube baffle kits:

Good luck!
