Favorite tests kit brands, let me hear them

I thought it was a bit more complicated to use than the Salifert kit
but overall I was happy with the test results obtained with it

my biggest reason for not continuing with this particular brand is

if you have typical reef parameters when you are testing, or parameters on the high side
you end up using a lot of reagent for the Mag test, but very little reagent for the Calcium test
which means you run out of the mag reagent faster than the calcium reagent
which I why I ended up using Salifert for Mag testing and then later for calcium testing also

with the independant products, you purchase just the one you need
