Well for the past 2yrs I've been using the API to do all my testing. I've been dosing ESV 2 part daily at 7.5ml. Have never dosed Mag. ( I do have some though) With the API my Ca=440~Alk=7.8~Ph=8.2
I finally broke down and bought a new kit. RedSea Pro. A little more detailed for sure. Hopefully I'm reading the results right. If I am then my CA 500~alk 6.4~Mag 1100. Not anything like what the API test was telling me.
I stopped dosing for a couple of days~did 5g WC. Tested again with same results. So 3 days ago I started dosing ESV Alk (only) at 10ml to slowly raise it. Testing everyday~As of tonight Alk still hasn't raised above 6.4. Tonight I also started to dose Mag at 20ml.
What I was to know is...Am I dosing right amount to raise the Alk and Mag. And can the API really be that far off from the RedSea Pro?
