that was my main focus in getting the refuge in etc, better water quality equals happier everything. the difference it has made in 2 weeks has already exceeded my expectations, especially considering its only a 10g DIY fuge i made after cracking one tank lol. the 10g was the only thing that would fit the stand i got with the tank(all free so who cares). but now i know what to do when the day comes to upgrade, thanks to the poeple in this club. hopefully i can pay for my membership tommarrow and be a full member.
