Aquarium Supplies

Used aquarium supplies for a ten gallon aquarium. Heater, filter, air pump, net, bucket, one air stone and left over air tubing. The filter does not include any carbon cartridges. The tubing is not the entire eight foot length. The bucket has only been used for changing aquarium water. There is some hard water buildup on the filter and heater. I plugged in the filter, heater and aerator. All are getting power and appear to be working.
