synergy reef overflow placement?

john.m.cole3 · Mar 14, 2016

the biggest down side to this overflow box is that I have the interior box jammed up as high as possible up against the center brace, and the water line is about 1mm UNDER the trim.

In case I want to change something later - won't have to buy 3 more bulkheads. Technically a union is good enough for that purpose but I just feel better with threaded.

john.m.cole3 · Mar 14, 2016

Do you feel that a threaded bulkhead will hold a seal as good as slip fittings? I;m only asking b/c I have no experience with threaded fittings...

don_chuwish · Mar 14, 2016

Yep, no worry there. Either tape or paste on the threads. Glued slip joints are technically better but I think it's splitting hairs.

I like the new plumbing! Nice clean drops, the 45's are perfect. Nice and simple!

very nice!
After I flipped around my bulkheads and set the tank up in the house, I noticed a leak from the bulkhead on the partial syphon line. A buddy of mnine had a spare bulkhead at his house. So, at 10 PM a unscrewed that bulkhead and caught the water in a mason jar, used PVC cutters to cut out the portion from the top of the union and above, and replaced that plumbing in under 15 minutes w/o having to drain the tank and pull it away from the wall (YES!!!)

this makes me feel better. My fiance just yelled out, "y'all both probably didn't read the instructions!" (guilty)

dang it John. After reading your posts I realized I glued in my bulkheads wring as well in the overflow box. It didn't leak during my test but I'm not taking any chances. I ordered new bulkheads and unions so I can fix it. It sucks because I was very meticulous and had the plumbing perfect

likewise brother. At least it's about a 30 dollar fix for a 200 dollar box! I re-used the bulkheads. Hear me out... I used PVC cutters to cut the PVC as close to the bulkhead as possible, flipped the bulkheads so nownthere is about a half inch of PVC coming out of the bulkhead in the outside box of the overflow, I got new unions and measured how much PVC would be needed to keep my plumbing the same, then got 2 couplings to extend the half inch of PVC inside the box for my emergency and spill over drain. Make sense?

Oh, but if you already ordered new bulkheads, you're good

Evening Gents, so I've had the overflow going a couple of weeks or more. Installed the new sump and cut the drains to fit. I still get a quick slurp sound every so often. I'm using a sicce 3.0 so I think I have 600 gph . If I made the full siphon a little shorter it would stop .
Also I'm not planning on putting screens on my stand pipes. I think the grate inside the tank will keep any critters out of the standpipes. What do You think?

john.m.cole3 · Mar 26, 2016

I don't have anything other than food that runs down the weir. I'm thinking I might need to turn off the return pump during feed time to stop getting so much solid stuff in my sump.

cracker · Apr 16, 2016

Hello Gents , It's been a while. so far the overflow has worked flawlessly. I shortened the full siphon stand pipe no more intermittent slurping sound. Good luck with Your installs ! Brian

Thanks for the warning on flipping the bulk heads. I would have made the same mistake. After that I did read the directions more thoroughly. I am hooking mine up to a 40 gallon frag tank. Drilling went great. Now I am just waiting for the silicone to cure on my sump. I was thinking of using a Sicce 3.0 but that may be overkill. I have a 2.0 and a 3.0 laying around.

anyone have pics of the inside of black box?
What size pvc did you use on inside of black box?
I bought the 16"in box...drilled tank just finishing up the stand.
Not sure how or what to use to complete black box.

I used 1" PVC and DID NOT GLUE. 1" lomg for full siphon, 2.5" for partial siphon, and 3.5" for emergency. The emegency never has water go down it, but the partial siphon does and its dead sikent behind the couch in the living room. All I can hear is a MJ pump to my reactor.
