DanesFish Posted August 1, 2013 Report Share Posted August 1, 2013 I have a Blue Ram in 30 Litres tank of Tap water with a pH of 8.0 GH of 12 degrees KH of 4 degrees Conductivity of around 700 uS/cm I wish to convert the tank to rain water... FYI pH 6.5, GH & KH undetectable. How should I go about it. I would like as much technical advice as possible please..!!! Link to comment Share on other sites More sharing options...
The Tech Den Posted August 1, 2013 Report Share Posted August 1, 2013 The best way is to use rainwater or a RO unit. 30 Litres is a small tank and water changes would be small. Maybe there is someone local with a rainwater tank that would let you have 5-10 liters every week or two to do water changes. PS If you have undetectable Kh and Gh you are likely to have a Ph crash and will drop to a Ph of 3.7 or lower. Link to comment Share on other sites More sharing options...
DanesFish Posted August 1, 2013 Author Report Share Posted August 1, 2013 I have a rain water tank. Since the only fish will be a single Blue Ram I doubt my pH will crash because I will be testing nitrates and do weekly WC. I would agree if I was going to CO2 inject but I have no intentions in doing so. If your serious about my KH I will look into aiding my KH and GH with bicarb soda or epson salt or maybe just a little rift lake salt but at this stage my only concern is safely converting my ram from tap to rain. I guess the first thing that would change by adding rain water would be the GH long before my pH shifts. I just don't know if 0.5 pH of a change would be too much per WC.

Rod Posted August 1, 2013 Report Share Posted August 1, 2013 I'd just do 20% water change each week.....with rainwater After 6 weeks add 10% tap water to water change... Link to comment Share on other sites More sharing options...
