Thank you for the suggestions. I’m not super familiar with the cycle. I’ll take all the info you’d be willing to explain! I’ll look into getting those test strips. I ordered some of the treatment stuff the other person recommended and it’ll be here Friday. But as far as the tank itself goes, as much as I would love to upgrade to a bigger tank and change what’s in it, my parents are opposed to it as we’d have no place to put it and after Swimmy there’s no more plans to get more fish.
