Med Laboratories Giant Banquet Block Feeder (3 Pack)

Very helpful if you are going away. My pet sitter didn't have to worry about feeding the fish and they didn't get overfed. Lasted 10 days easily in large tanks.

We have a litt- le 'pond' in our yard we stocked with cheapo goldfish. They have thrived out there eating mosquito larvae and who knows what else so well that they have grown from 1 inch to 4 inches over a couple years. However the pond does freeze over the winter. Our solution has been to set up a 50 gal aquarium in the garage to overwinter them . THe problem with this is we do take several 7-10 day vacays to warm climes in the winter and need to keep these guys fed.Vacation feeder blocks are the answer but the locally available ones are too small to keep 7- large hungry fish fed for a week. Yes we could put more in, but they dissolve too fast.Saw these and thought I would try them next trip. They were perfect! So easy to use! I tossed two in the aquarium before we left on a 6 day trip and crossed my fingers.There was no need to cross my fingers, these worked out great! They started dissolving almost right away and when we got back there was still about half the thickness of each block remaining on the bottom of the tank. The water in the tank had not gotten cloudy or stinky, and I did not see any weird residue and scraps of anything in the water or surface of the water. Fish were all alive and when I tossed in thier regular food they did not attack the fish food like they had not eaten for a week and were hungry. This tells me that they feeder blocks worked and they had enough food.Price was better than competitive feeder block and these worked so well I will keep some on hand.

Lasted the full two weeks. All fish were fine and water was clear when I came home.

Good price. Good product. Lasts as described.

fish are still alive so it seems to work
