Hi,
I have a relatively new system (420 gallons total) I set up recently with extremely low bioload currently. I have an Alkatronic/Dosetronic on it that initially was having to dose calcium/alkalinity (B-ionic) every 2-3 days to maintain a level of 7.8-8.0. This went on for more than a month until the last dose 8 days ago, following which the alkalinity increased to 8.15 and the Alkatronic has not dosed any of the alkalinity solution since then. However, my alkalinity has started to slowly climb on its own and is currently 8.6 (see below). I have double checked this with Hanna and it is accurate. I am using no other alkalinity supplements but am having to add Neophos and Neonitro to maintain appropriate nutrient levels.
Two questions,
1) Is the Neophos somehow displacing carbonate adherent to calcific rock leading to increased alkalinity?
2) I have a 1 M solution of HCL. How much would I need to add on a 420 gallon system to decrease the alkalinity back to 8.0?
Thanks!
Mike
