2part dosed quantity over the years, any change?

[Futuretotm]

Has your 2part dosing quantity changed over the years?
Thinking of taking the Trident offline after 3 years, its just headaches, my tank has been doing great with 130ml each of alk and ca for the past year now.....

180G heavy stock, started at 5ml per day, 5 years later,now 50ml per day.

Simple dosing, no issues.

The answer will depend on whether corals have hit a steady state of growth vs pruning, and abiotic precipitation, etc. but in many tanks the amount needed to exactly match demand grows with time and may vary day to day depending on pH (windows open vs closed, gas stove cooking a thanksgiving turkey, etc.)..

That said, daily dosing a fixed amount can work fine, and one may just find that dosing more means a higher steady state alk, but otherwise a fine tank.
