hey i just a new baby ray, been changing water every morn to get rid of tail fungus, now i've noticed i have ammon, i've never had ammon! would the addition of this ray spike this level? its just a very juvenile ray? the water changes are about 25%, maybe i'm changing to much and starting the bactieria process over. all rays are fine still even the juvy! i swear i have the hardiest retics in the world, if i didn't test i would not have known the difference with them, hte ammon level was .5-1.0, 0 nitrite, i always have nitrate levels, pretty high ones at that, i don't even test those anymore!
