55 gallon tank with Emperor 280, Aqueon 325, and Hydro Sponge III filters. 3 smallish goldfish (less than 2 inches). Lots of aeration. Feeding lightly (ProGold AM, peas PM). Water is warm (about 78) due to high ambient temperature and warm tap water.
I am day 30 of my cycle. There have been multiple bumps along the way -- removing all my gravel, accidentally putting chlorinated water in my filter box during a water change, inadvertantly salting to nearly 0.3% for four days instead of 0.1% (by using fine salt instead of coarse), etc. But early last week my cycle was looking really good. Two days I tested with no ammonia, low nitrites (0.25), and a few nitrates (5.0). I got my hopes up. Since that time things have gotten weird. I have pretty much been doing 25% water changes every day, sometimes 50%. I changed 25% yesterday, and this afternoon I had 1.0 ammonia and 1.0 nitrite
At this point I am wondering if I should break down and spend the $50 on BioSpira. I was really hoping to be done with daily large water changes by next week -- we are having house guests the 14th through the 19th, and having my Python draped all over the house is going to be a pain.
Any thoughts?
