Word to the wise: water changes is enough to introduce a healthy amount of natural occuring sea water elements in your tank! No need to dose, I am mainly using this to build calcium and ph/alk stability. I recommend for pico and nano tanks!
For all fluval edge 6g community: Dose 12 drops of A and B. Make sure you follow instructions and shake part B vigorously for five minutes after dosing part A. Add to area of strong flow.Hide

I got this to boost my calcium in my 14g Biocube. I started just squirting some of part A in, then 5 minutes later, squirt some B. I wasn't measuring and my parameters became crazy. Calcium was good, but Alk was sky high. I gave it a couple days rest and started using a syringe to measure the parts and everything is in check now. It doesn't raise the PH a whole lot. At least not as much as kalk.Hide
