Marineland pre-drilled 180 gal reef tank

cfloars · 05/01/2011, 07:48 AM

I purchased a 180 Marineland pre-drilled dual corner-flo aquarium. It came with overflow and return but I am having trouble setting it up. The return and overflow have male threads on the ends, and I am having trouble finding the correct fittings to connect them to my sump. Threaded pvc fittings don't work (different threading). I have tried hosing and clamps, but hard to keep from leaking. I have attached a photo of the connection. The connection is 1 1/2".

Does anyone have this type of tank and can recommend what type of fittings to use?

Any help is appreciated.

Chuck

Have you tried a threaded union?

the bulkhead accepts aglue in fitting the outside threads are for the retaining nut

This it what I had to make out of 3 pieces; I used 2 female threaded with a slip on the other side and used a PVC to connect using PVC glue.

I hope this helps

if you wanted to use hosing and clamps you need an adapter that screws on with a ribbed side to push the hose on and then clamp it. I'm not sure if you're going this route, but that is what I did on my tank. I did not have an overflow though and drilled my own.

did you take that piece to home depot and try different things? that is what I did as well. you can ask for help, but things like this really confuse them usually.

You won't find a PVC fitting to fit the bilkhead threads. You need to glue pipe on the inside and go from there.

And your retaining nut is upside down.

Thanks to all for the quick responses. I believe I have some ideas to work with. It has been a little frustrating, but that's just part of the "fun". I've only had two floods in the last two days

Had the same problem, I put 1 inch pvc in my bulk head as it is a "slipper" and not a threaded (on the inside). Then glued the pipe in. BTW PVC glue is ok and primer. I would wait 2hours for priming

You do know this thread is 3 months old, right?

I have the 75g Marineland, and yes i had a hard time with the fittings too, because the overflow kit said to use a 1" drain and 3/4" return. The thing they didnt mention is that the bulkheads are both 1-1/4", so i had to buy a reducer for the drain, and two reducers for the return. so it kinda went like this...

drain- 1-1/4"- 1"

Return- 1-1/4"- 1"- 3/4"
