Sorry for all the questions over last couple months, but I'm doing some changes and upgrades. I had reef tank for about 7 years. I think Im doing good after a lot of begining mistakes. I always used DI unit < made by one of the local stores>. Main reason was I did not want to waste so much water. I know many people still try to use it for flowers or other staff. Anyway I decided to buy now RODI unit. I need your advice what brand is the best. How many filters should I get. I see like 3 or 4 < three standing and one horizontal ower thouse three>. Please help me again. Thanks.
