Re: [AGA-Member] Potassium Test Kit

Hmmm. If the most it indicates is "2 or greater" and 2 is
desired, then it can't tell you if you have too much, only
if you have too little.

But it's easy to avoid having too little. Just add some
dipotassium sulfate. 
I guess you're supposed to test. And if you find out you
have too little, you start dosing and retesting until your
test results just reach 2.

(I put in about 3/4 teaspoon per 100 gallons of aquarium
with each weekly 50% water change. That should be plenty
and I hvae no reason to think that it's too much.)

Want to get dirty but stay clean?
