:-\My betta is in a 5g tank roughly about 5 days now. The water parameters were wonderful when i put him in(ph 7.2 as well)...I tested the levels maybe 3 days after i put him in it and the ph is through the roof(dark blue more than likely over the 7.6) and ammonia was .25 so i did a 30 % water change, and vaccumed his gravel. I tested the levels today and the ammonia is back down to 0ppm and the ph is still sky high! Also no nitrates or nitrites. What am i doing wrong? The only chemical in the tank is prime water conditioner. HELP!!
