Hello! I just recently ~4 days ago did a chemiclean treatment, but removed my blue sponge as a precaution as I've heard they don't mix well with chemiclean... any idea of when I can reintroduce it safely? or a best guess. I've done a 25-30%ish water change after the 2 day treatment period, but that's it. I assume its not safe to reintroduce yet? but any thoughts are welcome.
