Removes unsightly algae fast from your aquarium! Algae Control™ not only combats aquarium algae, it also works to keep it from returning. Algae Control is highly effective against green water (algal blooms), bluegreen algae, diatoms or “brown algae,” hair algae or blanketweed that grow on the glass and décor. Unlike some other products on the market, Tetra Algae Control can be safely used in planted aquariums. Tetra’s precision dropper tops help consumers administer the proper dose to their aquarium. One drop treats one gallon.

This product comes in the following sizes: 1.69 fl oz and 3.38 fl oz
It is a violation of Federal Law to use this product
in a manner inconsistent with its labeling. Before applying, first remove as much algae as possible by cleaning the glass and décor. This allows Tetra® AlgaeControl™ to be its most effective at reducing the remaining algae and inhibiting new algae growth. Remove activated carbon filters for 6-8 hours after dosing. Be prepared to clean out additional algae as it is killed to prevent deterioration of water quality.
Add 1ml of Tetra® AlgaeControl™ for every 12 gallons (45L) of aquarium water. DO NOT OVERDOSE. Adding Tetra® AlgaeControl™ in areas of high water agitation or by pre-diluting Tetra® AlgaeControl™ in a cup of aquarium water will help to distribute the active ingredient. Ensure the aquarium is well aerated.
Repeat if needed every three days for up to three total doses, then clean the aquarium of dead algae, and do a partial water change. For regular maintenance, use as algae starts to reappear.
ATTENTION: Do not use in newly established aquariums less than three months old. Do not use in aquariums with invertebrates or crustaceans e.g. crabs, shrimps, or crayfish.

Rated 2 out of 5 by from Killed my large healthy African chiclid I dropped the algae control to clear some brown algae attached to glass not sure whether i need to remove fishes before throwing this in. I sprayed in water circulator (catridge) and within few hours my 2 African chiclid died and rest are mostly inactive. Only difference from previous day is that i added few drops of Algae control from tetra, the fishes lived happily for more than 3 months and i didnt change the water in last 3 weeks..

Rated 5 out of 5 by from Aquarium Algae Control worked great I have a small aquarium and was upset when it turned green as soon as the weather warmed up. I used this product and was very happy with the results. The water cleared up and all the algae disappeared very quickly. Just two drops and the water was crystal clear the next day. Thanks Tetra!

Rated 1 out of 5 by from My 6 year old goldfish died within a day of using. Followed the directions to the sad. I wish I would have just scrubbed the algae off.

Rated 1 out of 5 by from It cleared our tank AND our fish! We experienced a huge algae bloom in our fish tank. We relocated the tank thinking that it may have been exposed to too much light. Then we did a 40-50% water change and replaced the filter. Nothing changed. Based on a recommendation we purchased this wretched product. We followed the instructions to the letter, and within 3 days ALL of our fish died- including our plecostomus, nails and newborn Black Mollies. So yes, this product got rid of the algae. Our tank has never looked better, but now it's empty....

Rated 5 out of 5 by from Does what iy says om the tin :) I've had an algae bloom problem for weeks, I tried replacing the water numerous times, cleaning the tank and equipment but within a day the luminous green water would return. The biggest problem is that the tank is in direct sunlight. I decided to try using this product.... Within hours I noticed a difference, by the next day the algae was gone, no more luminous green water.... Very happy with the results....

Rated 1 out of 5 by from sand would be more effective I use this in my 20 gallon tank, and even when i leave my filter out and let it circulate around for a week, it does literally nothing. It was probably the worst algae control product I have ever bought. Don't waste your money on it, go buy Jungle brand No More Algae. That stuff actually works, and quite well at that.
