Are their any test kits out there that don't require using syringe and subtracting what's used...etc?
Is there anything that you just count drops?
Think I have the red sea kit and its a pita.
Normally i would say +1 on the elos, but Which red sea test kit do you have? The newer ones with the new boxes or the old one? The new one is one of my personal favorite and very easy to use. Takes me about 3 to 4 minutes to get my result
