I have this wierd problem. I bought 2 different bags of monopotassium phosphate and made a pretty strong solution with it. (>10gr on 100ml water)
Both solutions don't measure any phosphates in it using both my PO4 profi test (drop test) and also not with my Hannah PO4 tester (digital).
What...
So yesterday i added 4mg of my R/O minerals to 20l water and got a KH of 1.3 out of it (i use a Salifert KH test) and a μS value of around 169; which is in line with the table above.
Would that be a good start? (I have yet to measure the GH value of that water to be honest, see below)
p.s. from...
Question; i have bought an HM digital AP-2 tester to measure my conductivity of my R/O water unit. I want to (only) use R/O for my new tank and i want to get it up to 3.5 Kh.
If i look at the manual from Dennerle Remineral+ for example it states:
So adding 10g to 100l gives you:
1.3 Kh
2 dGH...
Does anyone of you know if the formula for Sera Mineral Salt changed? I bought the product before to raise both the GH and the kH of my RO water, but now it says on the packaging that it does not affect KH (anymore?). Does anybody know more?
