Synergy reef overflow

[pserelis]

Does anyone have any experience with this kind of bulk head ? Tanks been dry for a while. Leak tested it and have a small drip by the overflow. Wanted to change the gaskets but can get the bulkhead to loosen. Any advice ?

I’ve had my best luck here using a large set of channel locks, or a strap wrench on each of these nuts… be careful though, these overflows are very fragile! — I definitely cracked, and had to subsequently repair mine while also doing a gasket swap!

(Worst-case, you can get the tip of a flat head screwdriver on one of those tiny nut ridges, and tap the screwdriver with a hammer to start spinning the nut loose… this is a last-resort, as there is definitely risk of damage!)
