HELP! Old tang not friendly with new tang

Sounds like an impulse buy. Just because you can get something "now" does not make it the right decision. Hopefully it lives and your mother's money is not wasted.

I moved rock around. Did nothing.

Is there any reason I can't keep a tang in the sump for a few weeks?

Should I just get rid of this tang?
