I did'nt see any website at the front or the back of the cover, and the above is all the info provided by the box. I place only one block, not in direct powerhead outlets, but it dissolved the next day, I wonder if the watchman goby EAT it!!!?? According to the
LFS, they said one block should last 3 weeks, so 1 day and 3 weeks is really too much a difference. If the goby really eat it, will it cause death? But I can't stop the fishes to eat it, since the block has to be in the water and with good water circulation, the fishes is such of good reach to the block.
