A while back I got into the lazy habit of buying "RO" water from my neighborhood market's water vending machine. Before I knew it, I was fighting a losing battle with GHA that almost drove me out of the hobby.

Nevertheless it has been worth the drive and now I'm algae free! I'll never use anything other than RODI again and I also just ordered a RODI unit from BRS on cyber monday, since the drive to the LFS has been getting old...
