Wow that's a big wrench. Whatcha using it on??

...troublesome threaded fitting on a true union valve. I needed a 1-11/16" wrench for a 1" valve. I wouldn't mind finding one for a 1.5" and even a 2".

I looked at an adjustable wrench of that size..$250!!! Awesome tool, though.

There's no doubt that warm SW finds a way out where cold FW can't.

Man I see myself just busting the fitting if I tried using something like that. Also broke far too many tanks overtightening bulkheads too (mind you smaller tanks with 1/4 glass .. maybe 1/2" and up is not so delicate). Just a thought, if it's a union that's not sealing, could you see about a new O-ring maybe? (as an alternative)

It's the threaded connection on the union, not the union portion itself. I was concerned about over tightening it, though. This enabled me to give it another 1/4 turn.

In most cases, I've found hand-tightening bulkheads to be sufficient as long as you have a nice smooth, flat surface to seal against. (Use good quality bulkheads!)

Oh ok, not the union itself, I see.

And yes, FWIW I agree, hand-tightening bulkheads should be all you need.

I was just saying, you can crack glass by overtightening those.

However ....

You can still crack open a FNPT to MNPT connection if you overtighten. I was doing the exact same thing as you about a week ago on 1.5" pipe, I just used a pipe wrench, and that "extra 1/4 turn" was all it needed to crack open. Just sharing some experiences... trust me I've found lots of creative ways to break things.

Yesterday was a good day. My first shipment of LR and sand arrived in Seattle at about 8PM last night (shipped from Tampa Bay Saltwater). A quick zip down to Seattle and back got the rock into the sump and sand in the tank by midnight.

150lbs of sand...250lbs of rock... Yes, I'm in the tank at this point...

I threw one particularly large rock into the tank and 2 mantis sprang out. By the time I'm done, I bet there are 12 or more mantis in the main tank. My intention is to keep the mantis, but I may hunt down the crabs. (then again, the mantis might do that for me...)
