API ALGAEFIX Algae Control 1.25-Ounce Bottle

It worked amazingly well.Crystal clear water after a few hours of first dose & no problem with the fish in the aquarium.

I've kept fish for 9 years now and had a bacteria bloom in my tank....I presumed too much natural light in the room where my tank is kept....however, this is where its always been?? Anyway did all the routine checks, water fine, do weekly water changes as I've always done. I know doing too many water changes can make the problem worse. I was a little sceptical at trying this product especially reading fish have died etc., but on reading up on this product thought I'd give it a go. I have 110 litre tank but just mixed 1.5ml of Algeafix into some tank water so basically 1/2 of recommended dose....OMG by the morning my tank is back to crystal clear again!!! Fish absolutely fine and do not have to repeat process 3days on as directed. It has definately worked for my fish tank but be very careful putting the recommended dose into the tank....start with 1/2 the recommended dose just to see if your fish are okay and maybe repeat the small dose again 3 days later if no better...but it worked miracles for my tank water and fast 👍

Got rid of my green water problem YOU MUST FOLLOW THE INSTRUCTIONS ON DOSAGE!!!Definitely use again

This did nothing for my water treated then repeated 3 days later there was no difference at all .very disappointed as reviews I read all had positive results
