Is leak seal tape marine fish safe?
I had a minor drip coming from my bulkhead elbow so I bought some leak seal tape instead of draining the tank and replacing the fitting. I was wondering if it is safe for the marine life.

why not replace bulkhead fitting? why you need to drain the tank to do so?

No idea. But depending on how the bulkhead is configured you might not need to drain. I've used plastic wrap to seal a bulkhead from inside the tank and tankrn thread entire plumbing offline on the dry side of bulkhead.

I have a glass holes overflow system. I would have to drain the tank down at least 6 inches to take the bulkhead off to take it apart and fix the leak. That would be if I didn't have to move the whole setup away from the wall to access it. my setup is recessed in a corner and I would have to pull the tank away to be able to work back there, for that reason I have to drain most of it before I can move it.

"leak seal tape" is a generic term..
Search for the SDS sheet for the specific brand you are using.. Not that it matters.. Its very difficult to say something is "marine life safe" without extensive testing that they simply won't perform.. JB waterweld works great though and its been used many times by reef tank owners without issue..

By leak tape, do you mean Teflon tape?
Teflon, by its nature, is nonreactive. That's why things don't stick to Teflon pans and why they periodically use Teflon beakers in labs. For what its worth, if Teflon was known to be dangerous or toxic, we probably wouldn't have it applied to our cookware. |

You do realize that teflon if directly ingested is toxic? Although highly unlikely as the chip would pass through the gastrointestinal track before causing any real issue, but it's possible. Also super heating teflon(above 500F) makes it release super toxic gases. There is a reason why they tell you to throw away teflon pans if the teflon is flaking off, and to not preheat or cook on high in teflon pans.

you said the elbow is leaking a bit right??? if its the elbow part I would just turn the pumps off for a bit so no water is running through and then just cover the fitting with pvc cement/glue. Making sure it gets down into the hole the water is coming through. The glue bonds the plastic together so it would seal the hole or gap the water is coming through. give it a bit to dry then turn pumps back on.

Are you positive the bulkhead isn't cracked? Elbows aren't all that easy to crack but bulkheads are notoriously susceptible to that one tiny bit of over tightening. I would buy a Brute, drain the tank, pull it away from the wall and be certain. Anything short of that may work but I'd always be wondering.
