I got incredibly spoiled while living in the NW and again in NC with the water ....... then we moved here to IN and I have found the water here is basically liquid rock!! DH's africans love it but I tend to keep fish that prefer softer more acidic water and I am about at my wits end. While they will live fairly happily in the water from our tap (treated of course) breeding has been a challenge. The addition of drift wood has helped a little but because our water is SO hard it hasn't done much. Everyone I talk to and everything I read touts the use of peat filtration to soften and acidify the water but I haven't really found anything on specific methods of using the peat. Has anyone done this and if so how did you do it? I have a spare filter that uses cartridges and I was thinking I could use an empty cartridge to hold the peat material and allow the water to filter over it that way.......would that work? I am very interested in finding a method to use because purchasing distilled water is getting a bit costly....and investing in a full-blown RO system is a bit much at this time.
