For some of us, our tap water is so bad, we don't have much of a choice. My tap runs about 40ppm nitrate, and has a ph of 8.5, and is hard as a rock. I have not found a good water mixture yet. I am still trying to get my Cacatouides to breed. --C. Alan ----------------------------------------------------------------------- -- This is the apistogramma mailing list, apisto@listbox.com.
