I'm happy enough with IO.
I use roughly 1300ml to mix 10g. If you want to be more precise, I use 128.81ml/g
This gives me 1.026 everytime. But thats my measuring cup and gallon measurements.
Sure it's big 3 params are a bit off, but I adjust/dose the new water before adding it to my DT. Usually I need to turn my alk pump down for a week as well.
The last few buckets have given me;
Alk 10.5
Ca 380-400
Mag 1380-1400+
This latest bucket is still 1300+ mag.
Yup, mag from IO has been high lately, but it saves dosing
