Alk question

[clevebill]

I dose 2 part when dowsing alk my reading goes from 150ppm to 155 ppm.I dose in am and check at night is that to much of a swing.if I dose again tomorrow same dose and goes up another 5 points then need to cut back on amount dose daily.I have a 110 gallon tank and start dose is only 10ml.I have only small spa frags so I guess there not consuming alot

I would cut back. That's just over 0.3 dkh increase so just measure every day and drop the dosage until it becomes stable

I switched back to kalkwaser from 2part. It is the best if you use in ATO, test alkalinity every
day, and give pump a vinegar bath 1x week
