Is the tank being cycled now?Hmm... Idea!
I'm thinking of stirring up the water, and cleaning up the intake sponge daily. Since the sponge is not my main biological filtration, I just use it to filter out large particles so they won't get in the filter, I don't see it affecting the the cycle enough to be a concern. The mix of stirring up the substrate, AND cleaning the filter... that may be.
How is everything now?
