Yup, Melosu is right.....
I did the exact same thing and after a few frustrating months I opted for an ro
unit. It's much more convenient too. Just remember to change out the filters and resin on a regular basis (thanks to Kurt for telling me that).
It's really easy to hook up to either a garden hose or use a faucet adapter for an inside application. Just order the adapters when you order the unit to avoid a needless hassle.
I've had my unit for about 6-7 months and don't have anymore cyano
Good luck to you!
