External Overflow Bulkhead Gaskets

[Patrick Cox]

My new Planet Aquariums tank and included tideline external overflow box just showed up yesterday and I have a question about the bulkheads that connect the box to the aquarium. My current tank has a Synergy overflow box and that box uses a gasket on each side of the aquarium wall. (First picture.). The Tideline calls for only one gasket on the external surface of the aquarium. Does this make sense? Should I be worried about leaks? (Planet aquariums is hard to reach.)

Thanks!

If the manufacturer said to place the rubber seal on the dry side, then that is what I would do. I have learned my lesson from the past.

It won't leak outside of the aquarium. The only concern is water slowly dripping past the threads from the tank to the overflow box if the return pump is off for a long time, but it will likely seal itself eventually.

Any sort of leaks are basically my worst nightmare, so I put gaskets on both sides and used silicone.
Probably overkill, but definitely no leak.

Where did you get the gaskets. I’m having issues with water leaking in the overflow box and overflowing sump when return pump is off.

I got a big generic square of gasket material from the plumbing section of the hardware store and cut out some circles using a box cutter
