So, I did a 50% change of the 5 gallon in hopes of removing the dividers (only for now, they will go.back once I get the email from my school)
And it was dirttyyyyy. There were so many little things floating in the water (poop, fuzzies, food, etc.) And I don't know why the filter wasn't helping. There was also this brown moss like thing on the skull decor.
I know that I'm not supposed to do a 100% chance because it will kill off the harmful bacteria, but I can't imagine keeping my fish in that.... also, I can't seem to baffle the filter right, so its currently encased in a red solo cup with two small cut outs for water to go through.
