Review on Penn Plax PBV14N Feeding Blocks by Veronica Wade

Will not buy this item again. I was gone for 10 days and when I came back the feeder was still intact like I just threw it a few minutes ago. I decided to leave it in the tank to see if it eventually dissipated as intended and it never disintegrated even after leaving it there for over a month. The fish were fine while I was gone because I had left another fish feeder (different brand) just in case and it was almost gone when I got home. I use a biofilter so circulation was great so that's not the problem. So if you buy this item anyway, throw another feeder in your aquarium just in case!
