pool filter stuck

I like Ed's suggestion of talking to local pool guy, but if you must solve it yourself, I would start by making a big replacement wrench out of a piece of 0.25" thick aluminum and then use that hammer on more substantial arms.

It looks to me like you should be able to fit an iron pipe over each end of your wrench. Using two people, one on each side, you should get the leverage you need.

Thanks all,
here is what I did.
razor blade and cleaned out the surface between the joint.
Sprayed PB Blaster, overnight and morning of.

I tried a wooden spanner, but it slipped and was "handle" heavy and slipped up over the 1/4 piece.

The pipe idea was my next thing--only pipe I had to fit over the wrench was 2 ways tubes and they were two heavy whole, and I was going to cut them.

so before the call to the pool company, I got ugly with it and:

use a small hand sledge and pounded it. The wrench didn't break and it worked.

thanks for all the suggestions.

Nice - glad it worked out. I figured the hand sledge route would work - while a cheater pipe gives you additional leverage, I would have worried about slippage or breakage. The sledge gives you the jarring effect of an impact driver and I figured that's all you needed to loosen things up. Make sure to clean those threads, don't let any of that sand get into them, and lube them with some silicone lubricant before putting the cap back on.
