For Christmas, I got a thing of marimo balls, about six in total. I read through their instructions a cleaned them excessively by rinsing them in cold water as the instructions suggested. I have no idea if the two are related or not (which is why I'm posting about this) but I did an ammonia test about three days after I added them because I had just cycled some of the water out and wanted to check how it was doing. My last ammonia test prior to the marimo balls was 0 ppm and the most recent one was 2 ppm. I panicked and did another water change with the tank and let it run for two days and I tested it again. It did drop from 2ppm to only 1ppm but I know that's still very unhealthy for the axolotls. I don't know if this is linked with marimo balls or with something else. I've been making sure to clean up their food they didn't eat along with any debris and I've been cleaning and changing their filters regularly. Does anyone have any suggestions? Should I take them out of the tank until it's dropped enough. The tank definitely isn't new, I got a bigger tank in November and I had it running without the axolotls for 14 days. Sorry if I'm ranting I'm just a little worried about it all.
