I did the test about 3 hours ago. . .the dang sand bubbled for an hour with just a little (1/4 cup) in a glass with ~1/4 vinegar and water!!!! I am seriously never buying Caribsea products again! That is bull that they say on the web site that it is inert and will not affect your ph or hardness. Needless to say I spent over an hour siphoning the sand away from the gravel. It took about a 50% water change to remove all the sand. So I refilled it with tap water. I added the chemicals I got today (Neutral Regulator and Discus pH) and hopefully everything will work. After 2 hours the pH is already down from 7.6 to 7.3 and that is with adding tap water at pH 7.6! I will check it tomorrow and hopefully soon I can add discus to my tank
Fingers crossed everyone. . . .
Thanks for all your help Dano!
