Hi Fin Sharks for Algae Control
Like everyone else, I struggled with spring time string/algae bloom. I used an algaecide, which I hated, because I saw it was hard on the fish.
Every time I would go to different koi places, I would ask what they do for algae control. Two months ago, I was told about hi fin sharks. I purchased a couple of baby hi fin sharks (not really sharks). I have no string algae whatsoever and wish I had found these a long time ago.
Anyone else have any experience with these?
