Ok so I built this thing and so far so good. I figured out how you start it. You just have to turn off the drains below the overflow and fill the opening left in the middle at the top. I havn't been able to test it out yet as I don't have a return pump for the sump and I have to build my refugium first so in the next couple of weeks it will get done and can post some pics then but first i'll leave you with this.

Are you planning on adding the strainers like they show on the website. I was thinking instead of cutting slits in the PVC you could drill a bunch of holes and this would serve the same purpose.

I am planning on bulding a Sump/Refugium soon and will use this type of overflow to get water into the sump.

I am glad to see that i sparked some DIY interest.

deffinetly post up some GPH numbers when you get the opportunity to test.

see how long it takes to fill a 5 gallon bucket and calculate from there.

Starting it is harder than I first thought. When I had posted last I had just done a quick tryout in the laundry tub. I was working but not 100%. I hadn't gotten all the air out of the siphon tubes. I had to twist it around in the tub to get the air our so it would work properly. So my solution is that I'm going to put a small drain cock at the top of the crossover in the siphon tubes so I can suck out the air. Hopefully this works.

I don't have a clue how I would figure out the max GPH. it kept up with the tap in the laundry tub but that is only 60 gph I believe. It is very large. I used 1" PVC . I guess as long as it keeps up with the pump I add to it iamb ok. I was thinking the little giant 4mdqx-SC it claims 1350 gph at 0 head and 900 gph at 5 ft head. I have about 3.5ft head so iamb guessing about 1100 gph on a 90gal tank would suffice. Also gonna add a scwd.

Did it really beep out the proper name for an item? At first i was like what did I write that was beeped out. Anyways I added the drain "thingy"(shut off valve) to the top of the siphon tube and is now a breeze to get started the only thing is its kinda ugly but the canopy will hide it. Hope fully I will get my pump in the middle of the month and then we're off to the races.
