Product Description

Tetra aquarium products are dedicated to helping seasoned hobbyists and beginners alike enjoy a successful, life-long aquatic experience. Tetra products build fish-, reptile-and pond-keeping confidence, one innovation at a time. Our complete line of Tetra nutrition, water care, filtration and aquarium products are designed to meet the needs of all hobbyists and the fish they love. Tetra Algae Control™ formula controls unsightly algae in your aquarium. This liquid formula is highly effective against algal blooms that cause green water and algae that grow on glass and décor, such as blue-green algae (Oscillatoria), diatoms - “brown algae” (Synedra), hair algae (Spirogyra) and blanket weed (Oedogonium). Tetra Algae Control™ treatment is safe to use with ornamental freshwater fish and plants. See product label for complete directions and warnings. Before applying Tetra Algae Control™ treatment, first remove as much algae as possible by cleaning the glass and décor. This allows the product to be most effective at reducing the remaining algae and inhibiting new algae growth. Use 1 mL for every 12 gallons of aquarium water. Remove activated carbon filters for 6 to 8 hours after dosing. Be prepared to clean out additional algae as it is killed to prevent deterioration of water quality. See product label for complete directions and warnings.

It works wonders!

Reviewed in the United States on December 16, 2013

Size: 3.38-OunceVerified Purchase

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 a quick interior glass wipe, and before I put in the new water I put in the pre diluted tetra algae control. Then I poured in my conditioned water, sat down to watch some football, and hoped for the best. It took around 5 hours for me to see hints of the blue background plus 3 more hours for me to read the numbers on my thermometer. By this time it was 1 am so I went to bed and woke up to a beautiful fish tank. The water was crystal clear. My fish were swimming normally and not one has died since. I was thinking that I'd have to do up to 3 doses to get rid of all the algae, but all it took was one to bring back my aquarium to perfect condition. Other reviews claimed that this made their tank cloudy or worse but I did not notice this because my water was already horrible. Please give this product a chance. For all you that are leery about "positive payed" reviews don't forget that companies also pay people to leave negative ones on their competition. Do as much research as you can and read reviews on other major sites that sell the same product. Follow the directions to a T and you won't regret it.

This works very well for my turtle pond, i only use it every other water change, it seems to last that long. i've introduced my friend to this product who is a new turtle owner and she's loving it too. the only thing i didn't like was that it said somewhere that this stuff can cause cancer. but i figured that just about everything causes cancer and this keeps the water clear enough so i don't have to clean her water every 2-3 days. Also note that you MUST clean your tank or pool or pond before applying this. if your water is already green and you are expecting this to clear up your worries, think again. this prevents algae, not clear it away.

100% works but might be a bit harsh

Reviewed in the United States on November 13, 2023

Size: 3.38-OunceVerified Purchase

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.

Not effective against green water when used as dirrected.

Reviewed in the United States on November 19, 2019

Size: 3.38-OunceVerified Purchase

This product claims to work against green water algae, which is actually phytoplankton by the way. I used is as directed making precise measurements with a syringe for the maximum of 3 doses over 9 days. It appears as though the green water problem has actually gotten worse. I cant say if it had any effect on other algae since I cant see it through the green water. Also, fish did appear lethargic and oxygen deprived for the first 4 hours after each treatment, but eventually came out of it. The tank has good circulation and aeration. I only had the lights on a few hours a day because that's supposedly supposed to help as well, but it didn't seem to help at all.

Update: I wasn't concerned with getting rid of the hair algae because my goldfish seem to like eating it, however I thought maybe the treatment wasn't working for the green water problem due to there being too much algae, so I cleaned most of the algae off the glass and did a couple nearly 100% water changes until there was no sign of green water. I then repeated the 9 day treatment as directed while reducing the light cycle to lass than 6 hours per day, just enough to keep the plants alive. Once again, the fish were stoned for a couple hours after each treatment and it this time it killed the cycle in my tank. The water was already like green Gatorade again by day 9. It looks like the traces of hair algae I missed are still alive as well, though that was not my target.

Amazing product - works extremely quickly

Reviewed in the United Kingdom on February 9, 2015

Size: 3.38-OunceVerified Purchase

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
