Alkalinity level

My alkalinity is at 88 ppm, what is the safe range, what is the ideal numbers that I should be shooting for and what are the effects of the low reading? Also, what types of buffers are the best to use to raise it up?


thanks, dan

Good old Arm and Hammer baking soda dissolved in fresh water will raise your alkalinity safely.

This calculator tells how much to dose

That said, I would make sure the measurement is correct before making any adjustments.

Here is a table showing the safe range. I would target somewhere in the middle. This allows for test kit noise.

What is your PH. ? These 2 are linked. But 7 to 10 dKH is target.

That is very low (4.9 dkh) you need to get it up to at least 7 (125ppm) for a reef tank

Dan,

This article has a table of nominal sea water ranges. This is one on Solving Alkalinity Problems.
