>>in dallas,tx water is hard...approx 200pm...am looking for an inexpensive >>way to reduce the hardess thakinginto accoun multiple water changes of >>30% or more are performed per week, thanks, russ I'm not 100% sure that I'm right about this but I think that hard water filtered through peat moss will be both softened and acidified. I know peat can be purchased very cheaply, in bulk from nurseries as I've just bought a 50 lbs. bag. I know the more expense peat granules I have in my Aqua Clear filter last quite a while so I would also assume that I will be able to treat allot of water with 50 lbs. of peat moss. I believe I remember someone telling me I could just put the peat in a bag an throw it into my holding tank (40 gallon trash can). I also remember something about boiling the peat but I'm not sure that is correct. I haven't tried this method yet but I would like to hear from the more experienced members to find if I'm sharing good info. If I'm right this maybe a very cheap way to soften your water. Alternate issue; I like to see the fry remain with their parents but don't believe they would learn as much from this as I do. Just MHO.
