My 140 gallon tank is running lower than I like on Alk and pH. Any suggestion would be most welcome! Alk is 7.68, Cal 455, Mg 1390, pH 7.87. I am dosing triton 4 part with 4 Neptune DOS pumps. Part 1 Mg is at 3mL per day. Part 2 Cal is at 2.5 mL per day. Part 3A and 3B Alk are each at 4 mL per day. I do small weekly water changes of about 15 gallons every week.
