I couldn't leave well enough alone.

I started screwing with the refuge today and decided I needed a longer flex hose on the drain. While trying to get the old flex hose off I accidentally twist the bulk head and now I have a slow drip leak from the bulkhead. I need to unthread, reset the o-ring, and then retighten the bulkhead. Unfortunately, the holes in the cabinet are only slightly larger than the bulkhead nipple.

Would you:

1) Set a dremel scroll blade at the width of the cabinet top and expand the hole in the cabinet top from underneath, with the full tank still sitting above, giving access to the bulkhead nut

-or-

2) Drain the tank, remove all the corals, liverock, sand, water, .... and then tip the tank and fix adjust

-or-

???

...I have a slow drip leak from the bulkhead...Unfortunately, the holes in the cabinet are only slightly larger than the bulkhead nipple...

I think I'd exhaust all possible choices before emptying the tank. I cant picture a scroll saw being used there, but I don't have one of those. I do have the discs though, so would probably hack out a hole that way.

best of luck.

You most likely got some sand or sediment under the o ring when it loosened up. To fix that usually you need to undo the bulkhead and clean up the o ring and where it seals.

I would see if you can router out a bigger opening to undo the nut because otherwise your options are not much else but to empty tank.

Thanks everyone. As of today the leak has stopped. As it was, it was about one small drip every 2-3 minutes so very slow. If it comes back I will expand the hole in the cabinet from below using a dremel with a scroll bit (looks like a drill bit but actually works more like a router bit).

...a scroll bit (looks like a drill bit but actually works more like a router bit).

See, now that makes perfect sense. I had a visual of an actual scroll saw type attachment in my head...:no:
