So I am back, finally cycled, and have proper information...which feels good! I made some important changes to how I handle my tank, redesigned everything, and fixed some errors I was making. One in particular was my filter. I had a filter rated for 2-10 gallon aquariums when I first started trying to keep snails, and I've upgraded to a filter rated for 10-30 gallon aquariums. So I didn't interrupt my cycle I've been running both filters side-by-side for about a week and a half now...but my two apple snails have something to say about the current in the tank! They stay stuck to the opposite wall right now behind a plant where the current is lowest. That can't be fun! With only one filter running in the tank, the current is much less...so a little bit ago I took the filter bag and sponge out of the small filter and stuck it in with the larger one. I just want to check in on here and make sure that's not hurting anything, even though I can't imagine that it is. The filter itself still seems to have just as much of a flow as when it only had its own cartridge...so can I leave it this way for a few more weeks until the larger filter cartridge is definitely established?
