How?
 

Hello,

I'm just wondering how everyone tests for Potassium and Magnesium in there tanks. I can't find test kits with them here in my City. Any help is appreciated.

you can order the magnesium kit on jl aquatics i havent found a potassium test on there but magnesium is more important. I am pretty sure elos sells a potassium test kit so if you call jl aquatics they could probably order you one and its free shipping if your over 100 dollars.

On JL, you will use the Zeovit Pottassium kit. It is very hard to use, I hated it and actually don't test anymore for that.

I use ELOS test kits for MG, Calcium and all the others.

Thanks all.
