Can I add a sump to stock ap without drilling?

Here is a diagram of my idea. Its kind of like a closed loop. I get 2 of the same powerheads one to siphon and the other as a return. Will this work?

No...for several reasons. If you want a sump without drilling, you have to have a siphon overflow box or elevated sump (above or equal to tank water level). If you go with an overflow box, prepare backups of some kind. This would include float switches or duplicate overflow setup. Everyone who has ever had one has had it fail. With an elevated sump, the water moves in the opposite direction. It is pumped up out of the tank and into the sump, then flows back into the tank via gravity (overflow box or drilled overflow).

Drilling is so easy. I would highly recommend it. I put five holes in a NC24. The whole thing took about 2 hours including setup and cost about $20 to do.

My only problem is the tank is stocked and running. I dont want to break it down just do do this so I might just go without.

And thank you.

you could try something like mine, but you will have to have it higher than your AP so that you have a gravity return to the aquarium.









Just an idea. I used a pump that I bought from Walmart in the second chamber. I could use a little larger pump, but I may have to mod it to do so.

Your thread is what gave me the idea. Thanks.

I have done what Tahlequah recommends too, with a fuge that was located above the main tank. Worked well, but make sure that your return hose from the upper sump is of sufficient diameter, and doesn't "bend" too sharply (use a plastic elbow of necessary), or you could have a flood problem/inconsistent drain rates.
