CO2 Scrubber recommendations

[santeeeyyy]

Currently have an Icecap K1 skimmer. I want to slap in a small CO2 scrubber in my sump to and run it for a week or two to see how much it affects my tank. Does anyone have any good recommendations that won’t break the bank? I have a 40 gallon so I figured an ice cap nano or medium would be ideal but I have no idea how to set up a co2 scrubber. I’m not a fan on how that specific scrubber needs something to hang off of.
