Pro Balance 14-Day Vacation Feeding Blocks, Fish Shape (2/Blistercard)

I used this product everytime I go on vacation and I have never lost a fish. My vacations are usually 10 to 14 days. It works.

My fish luved it. No fins nipped or cloudy water in either my 29 or 36 gallon tank. Fish ate it after 7 days. Angels are pigs and have well above appetites. Still i got home a day before it ran out

put this 'two week' block just before leaving on vacation.. The vacation turned out to be the vacation from heck, and almost twice as long, but my fish didn't starve. They took to it right away, and it was all gone when i got home, but the fish were only hungry, not ravenous.

Great for when your on vacation

I have a 3 gal tank and one goldfish. I broke it into a third(ish) and it lasted nearly 16 days. Only some debris left in the rocks but otherwise fish survived 8 days away from it and water was fine. Good product.

Product turned water cloudy with white film after less than a day. I’m glad I tried it out a day before we left so the fish were not harmed. I have tried other brands who didn’t leave water cloudy. Would not but again. Also, Amazon is not giving me return option- just asking me to trouble shoot online.

I have a 10 gallon tank and this worked great for my betta while on a 9-day vacation. I did have to clean the tank once I got home because it was pretty dirty from this product, but it kept my cute betta alive and happy while I was traveling. 4 stars because one of them was broken in half but it still worked. I would recommend this if you're traveling but if you have a smaller tank just use 1/2 of one. (I think they sell smaller size ones also)

Went away for 11 days. The fish was alive when we got home, one big goldfish. As others mentioned, there was some white residue, but not too bad.
