ya the thing runs great no problems thus far, i made about 25 gallons and is storing it in a new garbage can for top offs. i did a 25% water change with the new water. i also started doesing kalk the past 2 weeks and i think i found the magic number for my system its about 2 tbs per 1 gallon of water i drip a full IV bag every night witch is about 1/3 gallon. this seems to be the trick.
