Tetra Algae Control 3.38oz - Broad Spectrum Aquarium Algae Treatment (77184)

Amazon Customer: We have a small 5 gallon portrait fish tank that gets enough natural light shining on it that algae has been a problem. I’ve done regular water and filter changes but it turns green again in a day.

I put only 4 drops in the tank to start and that might have been too much! The water turned crystal clear and clean very quickly but it seemed to affect our snail.

At 1 drop a month this one bottle will last years! Very well packaged and looks great.

Jessica: The spout poped off when I was adding it to the tank and spilled most of the bottle in due to faulty spout and all my fish were dead in less than a hour due to overdoes of whatever the chemical is. So beware of the spout and make sure it's on correctly. 😔 my kids were very very sad.

Richard: I bought this for my outdoor fountain. The water was getting green and a few drops of this cleared it right up. (It's a smaller fountain. Not sure how well it would work on larger fountains).

Annie KayAnnie Kay: Baxter, my Half Moon King Betta, is a happy guy! This algae product has helped so much with algae in my 2.5 gallon tank. First I moved the tank to the master bedroom away from sunlight and that helped somewhat. Them I bought this product and with help from my husband (who is better at math, lol) we figured out to use an insulin syringe filled to 14 units for this size of tank, thus not overdosing. Perfect! Then, at the same time I add Aqueon Betta Water Renewal which replaces essential trace minerals to promote health, color and vigor in fish...another great product!

Mrs. A. K. Jukes: Amazing product. My tank has been cloudy for weeks, I haven't been able to do anything to get rid of the problem. I even took all the fish out and jet washed my tank (this worked for a couple of weeks but it came back again). Couldn't see the back of the tank at all and if the fish were in the middle they went out of view ude to the murkiness of water. I put the potion in (very tiny quantity - read carefully I only had to use 1.5ml) and within half an hour my tank was crystal clear again.
Excellent product. i am amazed

Melody: Do not pay attention to those negative reviews. I have a 55 gal fish tank that would get worse and worse, no matter what I did. I do a weekly gravel clean (got a couple goldfish) and a weekly 20%-25% percent water change but the water would continue to get worse and worse. It got to a point where I couldn't even see the thermometer in the back or the fish swimming at the rear. The water was a yellowish, a greenish, and a brownish mixture. Something drastic had to happen so I went online, bought this product, and read and re-read the instructions. Common sense and following the manufacturer instructions are vital for this product to function properly and safely. You need 1ml for every 12 gal. You cannot use this in a aquarium that has been established for less then 3 mo. You need to add this in an area where there is a lot of water movement or you need to dilute it in a cup of aquarium water. Since this was the first time I was using this product I decided to dilute it in a cup of water in case I made a mistake. One teaspoon is 5ml so I used that but didn't fill it all the way (if I did it would have been for 60 gal and mine is 55). I did a quick gravel clean up (5 gal removed) and...
