For sale Neptune ATK v2 (Auto Top Off) w/ extras

Works like a champ. No issues. Has been citric acid cleaned, so it's good to go.

I'll include an extra PMUP (gen 1) and 2 additional optical sensors (you can keep them as backups in case you ever have issues with the ones that come with the ATK)

Also, you'll notice it has a compression fitting for the fresh water feed line to connect to on the sensor assembly, I can swap that back out for the push connect if desired by the buyer.

Asking $170 shipped, including PP fees.
