I gave up long ago trying to lower my high PH, not even tannis from my large un-boild mesquite tree limbs can put a dent in my 600 ppm Cal/mag water. All my fish are acclimated and especially my Mbuna that love this water. I was originally going to send a photo to Pet Solutions of the spilled Meth-Blue to get a replacement bottle but seeing how only a teaspoon full was missing Ill accept as is no big deal. Since the Meth-Blue will be confined to a cheap 10 gallon tank I think I should give it a try since breeders claim it works for Oscars. This will be my 3rd try battling egg and wiggler fungus so Im hoping using this stuff gets me to the fry stage where no meds are needed.
