ok ill try that and ill be putting sum silicone on the outside

Be careful with the silicone, it makes overtightening the nut very easy. You don't want to tightent it to the point where the gasket squezes out. Just tighten it enough to the gasket starts to squeze out then let the silicone cures. Once cured, you can tighten it more if you feel the need...

Actually, the gasket is supposed to be on the side of the bulkhead that DOES NOT have the nut. It doesn't matter if it is on the inside or not.

Yes you are correct. The gasket always goes on the flange side of the bulkhead. I was assuming that the nut would be on the outside but that's not always the case. Thanks for clearing that up.

Actually, no offense, but you guys are probably wrong. Secondly, never use silicone, as it does not bond well and is only a temporary fix. It WILL fail again in the future.

He mentioned he was getting the Rubbermaid Poly container. This comes with a super leak prone dual gasket bulkhead. It is not really built for our use.

The common solution to the problem is 1) if you don't really like that stock location, seal it off with a cap and drill a new bulkhead hole 2) replace the leaky bulkhead with one of our real aquarium ones.

I'd recommend a Schedule 80 bulkhead from Savko.com. Remove the old bulkhead, and measure the pre-drilled hole size and get one that fits, or take a Dremmel and very easily widen it to the next size up.

This is from experience My new system is online, but I still need to do electrical and other tasks as you can tell.

I assumed (possibly incorrectly) that he was going to replace the standard rubbermaid "bulkhead" with a standard one since the rubbermaid bulkhead is problematic and the opening is way to small to be useful. And on standard bulkheads I am indeed correct in that the gasket always goes on the side without the nut, not nessesarily on the inside.

This is from my experience as well

i ll have to go to my lfs to get the bulheads then, also rokle, how did you baffle ur overflow???

From what I've read, a lot of people don't realize this until they have them running. As well if I remember correctly, the stock bulkhead is 1", which is adequate for many uses.

This is very temporary as I'll have a new external skimmer soon. Many people use buckets or additional tubs inside if they need a regulated constant height (for like a skimmer). Water will slowly flow over the side of the bucket wall. If you are worried about bubbles, with a sump of this size unless you have frags/fish/etc in the sump, bubbles aren't much of a concern. They are gone well before hitting your return pump.

If you search (do it for like a year's time, not a month or two) for some items like "rubbermaid sump", "poly sump", "100 gal sump" you will get a few dozen pictures of setups people have put together to give you some design ideas. Hint: eggcrate is your friend in these large sumps

should i have the water al least flow into a bucket so there isnt that much turblunce in the sump, also the return hole is obviously near the bottom so does that mean that the airbubbles wont be able to get down there because they float up, in turn there wont be any???

 

[fishking]

im also putting a rr storage tub on top of the sump its self, as a refuge

 

[RokleM]

Without knowing what all equipment you're putting in there, that's hard to tell. I'd recommend running your pump in a loop, see how it works, and adjust accordingly.

ok im gonna be using a panworld 200ps, i have a ball valve for the return with 2 inch pipe, my tank is a 210, ill be using a asm g4x skimmer and a berlin skimmer for ozone, ill also be putting a phosban reactor.

 

[fishking]

well im gonna use a rubbermaid 37gal tub with sum holes on the bottom facing opposite to the return suction hole, ill prob put my skimmer in ther also, im will also be using a filter sock, i have an extra one too.
