Cleaning old decorations?
I just got a used 50 gallon setup that used to belong to a friend's mother. She passed away and the friend didn't have any use for the tank so he gave them to me cheap. Some of the stuff looks like it was left sitting for a while while the mom was sick. Lots of calcification on the tank and filter, and several of the decorations I want to use have old algae caked on them.
What's the best way to get calcium(?) off the tank and filter, and what should I use to clean the caked algae off the decorations, including a chunk of driftwood?
