RO/DI

[Jack]

Hey, I was just wondering if everybody uses RO/DI water. I hate algae and it is driving me nuts. I have my sand bed covered in the blue/green flimentous aglae. I hate it, so anyways, just wondering where the best deal is to get one. JL's got the kent 50gpd RO/DI for 330$. Is that the best? I just want some input and info before I begin purchasing. Also it would be good to know what you guys are using and works and what doesnt. Thanks
