Greeting reefers!
I drilled a hole in my house and ran a fresh air line to my skimmer which gave the same impact to my pH as having a kalk reactor without the maintenance. I live in the hippie part of the city so none of my neighbors do any lawn treatment etc but figured I should still have some carbon for like wildfire smoke, car exhaust, etc and piece of mind.
I built this guy out of 2” pvc and filled with carbon and a little wad of poly fill on each end. Just used some thread tape to make it air tight. Is there any way to decide a good schedule to change it on? I‘m thinking even if I do it quarterly it will be a very minor cost.
