I collect the RO water in a 35g drum then change it to a 50g in the heated fishroom and add about another 10g from the so called "waste" barrel then add 7g from the water heater which is 130 degrees. This usually brings the temp up to 80F and a hardness of around 50ppm and haven't used any type of dechlor in at least 10 years. ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
