Aquarium Advice FINatic
so i found an old fountain thing my mom had and took the pump out of it, looks exactly like a powerhead, suction cups and all.
but it was covered with white calcium deposits. I scrubbed most of it off but some is left in some of the cracks.
will this be ok to put in my fish tank or should i make sure to clean it all off?
