Two Part B-ionics
Using a two part dosing system has brought great stability to my tanks water chemistry. Specifically calcium, alkalinity, magnesium and indirectly pH
Interested in starting? Here is one way to do it
first check out your mag levels and use kent tech-M if needed to bring them up to 1300 ppm
to bring up your calcium level try Kent turbo calcium--it is a chloride so it won't affect alkalinity levels
Here is a suggestion
bring up your alk levels with kent super dKh (8-11 dkH)
bring up your calcium levels with Kent turbo calcium(400 plus ppm)
and bring up your mag level to 1300ppm
Go on the suggested dose of two part for one week
Remeasure and adjust the amt of two part accordingly
Repeat for another week and repeat the above procedure
Continue for one month like this and you should have stable water chemistry
