I never really considered just emptying out the chambers a bit.
If I were to go that route and drill out 1 hole in the 3rd chamber how far down from the top should I drill? And what size would you suggest. Something to run 1"OD pipe?

If you drill down low you'll have to use a 90 and a stand pipe if you drill high you can use a strainer in the bulkhead.

1" is to big there's not a lot of room so go 3/4 Max, half would handle it but I personally don't like 1/2" plumbing.

After you drill ahopvacshopvac to get out glass pieces and dry with a papertowel I would also drain the chambers completely

So I should run 3/4" pluming?
Standpipe inside 3rd sump should work. Leading into ridged pipe on back of tank then into flexible vinyl style to reduce friction loss into sump.

No problem there. What size bulkhead and diamond hole saw should I get to accommodate going 3/4".
For my pond I typically use unseals because there easy.
