Lately, I've been having an issue where excessive moisture is building up in the CO2 canister and getting the soda lime (Jorvet) wet, which rapidly deletes and renders it useless. I do have a moisture collection container (food canister with 2 holes in lid) between it and the skimmer collection cup/recirculation lid. The moisture collection cup is doing it's job but moisture is still condensing inside the CO2 media canister. Any tips to help prevent this?

I would stop recirculating it.

Recirculating can have some big downsides including condensation but even worse is the lack of oxygenation from the skimmer

I had that problem too then I stumbled upon the scrubber sold by FishOfHex. You can buy the whole scrubber or the part that removes the water before the media . I bought the whole scrubber and love it. Works great.

I'll check it out. I'm actually using his printed recirculation ring on my skimmer.

I used to have this problem, I added an equal sized RO canister first as water trap, but then most important was raising CO2 scrubber above height of skimmer cup, this seriously reduced the issue.
Finally cured it by ditching recirc CO2 scrubber in favour of fresh air line to outside. Sold on the remaining 12L of unused Soda Line and bought lots of beer. Girl with a master plan, hooray! 🍻🥳
