I wouldn't recommend those vacation blocks. AFAIK, they fugly up your water and overfeed your fish in one go or someting like thatAlternatively you could try one of the pellet things that dissolve over time.
I don't recommend using those. I put one of those in my tank and when I came back 5 days later my ammonia level was shot, and i had massive patches of string algae about 4cm long. And right when i put it in I noticed that it was allowing a LOT of fish food out, right from the get go. So if you're on a vacation.. you'd be better off not feeding the fish.Holly9937 said:Alternatively you could try one of the pellet things that dissolve over time.
