seems like a planet tank is not too far off from having a reef tank? im reading on some sites some do weekly 50% water changes, on my 10g reef i do a weekly 10%. are there different stages of maintence with planted tanks? weekly, bi-weekly, to monthly? will the ecology book discuss this, or do any of you have a tank which you maintain weekly, bi, or monthly? i would like to know. the weekly water change is kinda starting to turn me off. i use water from the supermarket for my ten, to keep my hair algae from having another "party like its 1999" fiasco. is ro/di water recommended for planted tank as well? i guess im trying to hear from the folk who change weekly, and what they have, and the bi, and monthly cleaners, and what plants and fish are in there, and dose. im not looking to use co2.
