Re: Ph Troubles
Thank you for the kind words. Check the pH of the buffered RO water before you add it to the tank, which should be a bit higher than 7.5 in RO water. Then if the pH is decreasing in the tank gradually then you need to add more Alkaline Buffer to the tank itself because you have something in the tank water driving the pH down. That could be organic acids, low KH, or the test kit for the pH needs to be checked. Checking the pH of the RO water will be a good indicator of the kit because the pH should go be around 7.8-8.0 initially.
