API ALGAEFIX Algae Control 1.25-Ounce Bottle

Worked a treat for me, I see a few negative comments but all I can say is make sure you follow the dosage. Remember if you have a 100l tank, you don't dose for a 100l tank. Remember to take into account your gravel, ornaments etc as that will reduce the capacity of water it holds. Therefore to be safe always slight under does, yes might take a little longer to get the effects you want, but it's far safer for the fish. It is very effective and provides outstanding water clarity. Therefore for me it's great value for money.

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 👍

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

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

Didn’t work for my tank unfortunately.

Does what says on packaging

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

Its waste of money, dont buy with positive rev, go with hydrogen liquid instead which is much cheaper

It helps if you use it in moderation but you have to follow through with everything else. It's not a magic elixir and you have to use common sense. You need to make sure you do your water changes, make sure you clean the tank, and make sure your parameters are correct and this will help.

Yeah the stuff works a little too good. Killed most of my guppies. My pleco is still good as far as I can tell. The guppies I wasnt too concerned about since I only paid $1 for 7 of them that turned into about 30 since there was a female amongst them. I have a 20 gallon tank and it called for 25 drops per 10 gallons so I used 50 drops. So beware of this, maybe start with a smaller dose. The algae is definitely gone along with the fish too, lol.

Awesome. Thought i was never going to get my tank cleared up and it worked within 1 hr.

Amazing product! I bought this for my daughter’s fish tank. It cleared it up it seems immediately! Highly recommended product.
