Hey guys, i picked up an ibc from a tank shutdown yesterday and was given a whole heap of stuff for basicaly nothing. Some of the stuff i know about but i was given 2 protein skimmers that im not sure about. One is a large reef octopus (not sure what model has some pattern engraved on the lid) and the other one is an aquamedic turboflotor 1000. Are these any good? Any input appreciated. Thanks
