That was my first thought. But water tested the same as my RO water (my new water for a waterchange) albiet a higher phosphate level. I am going to let the "soup" mix for awhile and re-test. I hope everything is good. Good thing my livestock and rock is in another tank...put everything in a 110 to repair a leak. So new tank is filled but filmy. I've used tap water for a lot of years and never really had a problem. Found a diatom filter if everything tests okay then i will purchase it and let it do it's magic.

On a side not, my alk and calcium tests are older..they are salifert but maybe i should get some new ones. Hmm...and an easy blad attachment my arms are only so long. Sorry for digressing..my mind works weirdly and my fingers just type following suit
