I have recently acquired a juvenile axolotl and aside from having some fish when I was younger, I was not prepared for him. Currently he/she is in an uncycled tank that I am working on cycling now. Daily water changes to combat ammonia spikes have been constant, testing water parameters multiple times a day. I purchased a pre-seeded/cycled sponge filter from Angels Plus and placed it in his tank last night around 8pm. It arrived in a little under 2 days, sealed tightly with some nasty water. Emptied the nasty water in the tank as well. I do have a couple of questions regarding this filter and how to ensure I maintain the nitrifying bacteria and not kill my axolotl in the process. I am currently using the angels plus filter as my primary filter. So far no nitrites and no nitrates. Approximately how long before I start to see a change in ammonia readings? Today the ammonia was at 1ppm. I changed about 50-60% of the water and got it down to .5, dosing with Prime for all water changes, and to detoxify ammonia as well. Will the water changes effect how quickly the preseeded sponge will cycle my tank? Are his ammonia levels going to be enough to maintain the bacterial colony? His well-being is the most important factor, but I’d like to get his tank cycled as quickly as I can. Any help is appreciated!
