Removes unsightly algae fast from your aquarium!

Tetra AlgaeControl™ not only combats aquarium algae, it also works to keep it from returning. AlgaeControl™ 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 AlgaeControl™ 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.
Aquarium AlgaeControl is rated 3.4 out of 5 by 14.
Rated 5 out of 5 by from It really works. Strongly recomend it. My aquarium was really much effected by algae. I cleaned aquarium and reduced the light to restrict algae grows but it didn't help much at all. I bought "AlgaeControl" to see whether it will work or not to handle with algae. I was so happy to see very visible effect after even first shot. I added it as described on the bottle three times and have no any problems with algae anymore. Thanks to Tetra "AlgaeContrlo".

Rated 5 out of 5 by from Fish must be tough I read reviews for first time yeterday after looking for dosage online. I have to admitt I have been using product for a year before checking dosage. I have been over doseing big time. Just to control algae on glass. I have had my goldfish for 7 years now they are beautiful. I guess from reading other reviews my goldfish must be tough as nails. Because tetra has no effect on them at all. It does a great job keeping my tank looking great. But also my tap water has clorine in it and that doesn't bother them either.

Rated 5 out of 5 by from Very helpful product I have used this product for a long time with no adverse effect in my aquarium. However, I have not been removing the activated charcoal and now just wondered about that. My question was answered and now I will remove it for a few hours to improve the results of the product.

Rated 5 out of 5 by from It's an amazing product. All right everyone say hello to my little friend. :-) please allow me to start by saying I am not a fan of using chemicals at all. Heck even my garden is 100% organic I raise my own chickens and hunt a lot of my own food. However sometimes even poison can be a good thing if used wisely and carefully. For quite some time now I have battled Green Spot algae to no avail because even in healthy tanks with bright lighting you're going to get green spot algae on leaves no matter how healthy your plants may be. But for me the real problem started about a month ago when I had a lot going on and so did my wife. We had a brief failure to communicate and she thought I was forgetting to feed my fish LOL. I am not saying anything is her fault at all. But the fish ended up being fed double time everyday for about a week meaning that I was feeding them their usual amount which is slightly too much and my wife was feeding them her usual amount which is a very caring healthy motherly dose of too much. And boom that was a recipe for disaster. In no time I had pea soup for water even though my aquarium is heavily planted and I have a filter big enough for a tank twice its size and a powerful water polisher there was nothing I could do to remedy the green water algae. I was even doing three 75 percent water changes a week to no avail. Then I started seeing hair algae Black Beard algae the Green Spot algae got out of control and the brown algae went crazy. It got so bad that I was to the point of nearly hanging up my hat. I did a lot of research and refused the idea of chemicals. Then the other night I did what I should I have done in the beginning I listened to my wife. We were in Walmart and she pointed this stuff out to me. The main reason I was so scared to use this chemical was the fact that algae is in fact a plant at its lowest form. So it made no sense to me how a chemical could kill one plant while sparing another. I took the chance and still skeptical I dosed my aquarium with half the recommended amount. I then took my seat in front of the Aquarium and watched the white filter pad on my water polisher turn hunter green within 5 minutes. I took the filter out gave it a good wash replaced it and sat back down to see my aquarium turn crystal clear Within 30 minutes. Now completely astonished I approached my wife saying well honey you were right and of course I got the mmm hmmm I told you so bit. LOL then I gave her a big kiss saying well I'm very glad you did. I have held back on Advertising for this product until today because I wanted to make sure none of my plants or fish were affected. And as I had hoped nothing went wrong at all. That is at least with my 20 gallon tank. In my betta tank it caused an ammonia Spike. I believe this is because I used the full recommended dose and the betta tank is very small. It says on the instructions on the bottle and on the website that this should not be used in newly set-up tanks. This is because not only does it kill algae but it can harm the beneficial bacteria in the filter system. So really I should say use it at your own risk and be sure that you do not have any snails or crustaceans including invertebrates in your aquarium. Because it says on their site it will kill them deader than a doornail. with the first dose. I also wouldn't recommend using it at full strength seeing as a half of a dose was like a tactical Warhead for my problem. But this stuff is no joke it decimated all of the Green Spot algae and destroyed the green water algae and it is taking its time on the black beard but it is melting it away and the brown algae threw in the towel the first day. I apologize for being long-winded but I am quite ecstatic about the results of using this product. So thank you for your time and I wish you all the luck and Fortune you can possibly have. :-)

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!

How many times do i put the algae control in my 55 gallon tank

Asked by: Enlightened One
If you are treating for an actual algae problem dose once every three full days or 72 hours. Do not do more than 3 doses, before doing a partial water change and running fresh carbon for 24 hours. If you are using it as a preventative, one dose per month should be sufficient. BREX

Do I add algae control with fish in aquarium?

Asked by: Emte
Yes, you would dose the tank directly, with the fish in the tank. Be sure to do a partial water change first, if it has been a while since the last one. Also, keep plenty of aeration going. BREX

when will it be safe to reintroduce my invertebrates to the tank?

Asked by: mike72
Thank you for inquiring about this product! Once the algae is gone, do a 30% water change, and change out the filter media. Wait about 24 hours, and then place your invertebrates back into the tank. BREX

how much algae control would I need to use in a 150 gal pond ?

Asked by: gordy
We appreciate your interest in this Tetra product! This is actually designed for an aquarium, and is not recommended for ponds. We do make a pond formula, however, and I will provide a link below. Typically, if you live in a part of the country where the water temps are less than 65 degrees currently, you should not use Algae Control until next year or once the water temps are at least 65 or higher. In the meantime, you would dose only 10 ml or two teaspoons for a 150 gallon pond, when using: BREX

How many drops do I put in a 68 gallon tank

Asked by: Eric2
Thank you for asking Eric2! Use 1 drop per gallon or 1 teaspoon for the entire 68 gallons. We recommend a partial water change first, to ensure your water quality is good and the alkalinity is buffered properly, prior to use. Remove your carbon for about 4 hours, then put it back into the filter. This is a slow moving chemical, so expect it to take up to 72 hours for you to see results. Killing off algae too quickly can deplete oxygen in the tank, and the toxins from the dying algae can overcome the fish. Let us know if you have more questions! BREX

Can it be used with my slider turtle ??

Asked by: Massagelady1699
We appreciate your interest in this Tetra product! No, it cannot be used with turtles, as they absorb chemicals through their skin. The best way to control algae in a turtle tank is to do weekly 50% water changes. Also, make sure you replace your light bulbs at least every 6-12 months, and do not leave them on for more than 10 hours a day. BREX

Thanks the algae past away, but I have to put all the 50 mls. in my tank of 300 lts. including the sump water, Iwas cycling so I dont have fish in my aquarium in that moment, so what I do now? So I can introduce fish in the aquarium.

Asked by: JERRYRM
Once the algae is removed, just do a partial water change and test your water quality. If the water quality is okay, then you can go ahead and begin adding fish. Add 1 or 2 at a time, and no more. Wait at least a couple of weeks before adding more. BREX
