hi

I knew it was a good idea drilling the tank...that looks way too complicated for me. Keep us updated on how it works though.

i dont know the exact gph of the overflow but ik that it has a decent flow and holds a siphone wen the water drops below the intake

When I had a 40g running parallel with my main tank, I used the same siphon design between the two tank as well. Worked really well. Never lost the siphon between the 2 tanks.

here are some pics of my diy pvc overflow

FTS i know its crocked i just haven't bothered starting it yet


entering the sump ....there is quite a bit of flow


shot of the sump


return line flexible high pressure tubing i think..lowes was out
of regular tube so i had to buy this

all together I'm pretty impressed with the overflow like i said before i don't
know the GPH but it seams like a lot of flow to me it keeps up with a 300
GPH pump turned down a lil I'de say its closer to 250GPH...i think all the pvc
and elbows came to like 12$ I'm much happier paying that instead of 130$ for
a HOB overflow box

I would suggest making the pipe that enters the sump longer, so that it discharges underwater. You are going to get a lot of noise and splashing if it opens up above the water like that. But it looks good!

Another thing I would like to point out, is in the last picture. Those fittings arent for that tubing. Those are PVC 90's. I wouldnt trust the glue to hold the tubing in. Especially under the presure of the return pump.

But the overflow looks very nice. Glad it is working out for you

if the water discharges below the sump water the bubbles from the over flow break the siphon i had to go back to the shorter pipe

You could try putting a filter sock on the end of it. It would help keep the splashing down.

I just made this same overflow for my aquarium and I've only dry fitted it and tested it with a trash can and I'm going to cement it tomorrow before I start using it....do you think if you put the return below the water, and then put another elbow under the water that would stop the bubbles from breaking the siphon?
