After 2.5 months of no fish the 7 gallon tank still HAD not cycled. I've posted in previous posts about this. After a bit of back and fourth I've decided to basicly restart the aquarium by dumping out 90+ of the old water and adding all fresh water without cleaning the filter so not to kill all the bacteria if there was any. I made what I think now was a mistake of adding my beta, Mr. Sparkles, into the large aquarium from the bowl I previously had him in. So now the ammonia levels are sitting at 0.25 vs the 8.0 previous reading. Big question is now what? I'm real worried Mr. Sparkles got poisoned and may die as an end result. If he does I'm just going to buy a few "feeder" fish and let them help the cycling as I know it's better to cycle an aquarium with fish vs empty. I love my Mr. Sparkles but have no way to treat him other then what I've done. So what I need to know is just how frequently should I be doing water changes and just how much of the 7 gallons should I be taking out? I'm frustrated to a VERY high level at the moment.
