My tap water, im guessing, is ro filtered, cause it is VERY soft to begin with. i have some kind of clear slow disolving rock, abf Trxas holy rock, the lfs recomended to harden water. The tap is pH 6ish. I tested the water the the day adter i placed the wood and did a 50% water change, and noticed the tea colored water. Thest said the pH was really low, and was super soft water. I added a neutral ph buffer, and a pinch of baking-soda. Ph will be at 7 for a little while, but with no minerals to buffer it, it will spike. The frogs (7 fire-bellies) have been with this water condition once before, but it didnt stop them. This is the first time they've avoided the water. The fish (2 rosy red minnow, 3 zebra danio) are all doing great in there, as well as the mystery snail. They are ALL eating just fine, and the males are chirping normally...
