I recently cycled a 10gal for my Betta, and have added three new Corys so far (figured I would let them settle in a bit first). All my levels are great except my Ph! I can't seem to get it to go down (currently at 7.8 ), and don't want to put LuBu in there while it is high like that. The Corys are doing great (so far).
Currently I am using spring water for LuBu (Betta), but I can't imagine using gallons of spring water every time I have to change out the 10gal.
FWIW, our tap water has pretty high ammonia and Ph, so along with a water conditioner, I use Ammo Lock for the ammonia. I have put some Ph down in the water three times now (although now I have read that is stupid because it causes too many fluctuations), and it has not changed it at all.
Any advice is greatly appreciated!!
