Zoo Med Laboratories AZMBB4 Plankton Banquet Block Feeder Regular

We have 30 Cichlids in 135 gallon aquarium. Used 4 while we were gone for a week! There was just a tiny bit left. Each time since we have been gone, they swarm our hands when we put them in the tank! Going to be gone for extended period I would recommend this brand!

Worked as intended but I came back and the fish tank was disgusting. I usually do weekly water changes (even though the water is visually clean) and I was only gone for 10 days. My fish was fine and healthy but upset and stressed that I had to deep clean her tank.

left for long weekend put this in tank fish did great did not cloud tank worked good just removed what was left when got back home. works great

We went on vacation and added one of these before we left. We came home to living fish. So... it worked!!!

Fish were alive after a week at the beach. Served it's purpose. I've read about some other products that crumble and fog the water; this did not do that. I would buy again if needed.

We used it to go away for 5 days. Only half the fish were still alive when we returned.

I left this in my 15 gallon tank with 4 saltwater fish. I was gone for 7 days and returned to all the fish alive and healthy and the water clear. I did perform a water change after returning home. Fish are still healthy today (a month after my trip).

Used while on a 5 day vacation. Came home to having some still in the tank. Tank was clear. No cloudiness at all. Will use again for next vacation.

My shrimp went crazy for this stuff. So did all my fish. Lasted exactly a week and everybody was alive when I came back home. In fact, I came home to a bunch of my guppies having given birth and my shrimp eggs hatched. Clearly they were thriving on the stuff. Will buy again!
