No More Algae Tablets for Aquariums, 8 Count

No matter what I did the algea kept growing...this was my last ditch effort before returning my fish to the fish store. I was amazed at the results in 24 hrs. Highly recommend for out of control algea issues. BTW my fish were not affected at all during this process either. I tried everything even changing tank water. Attached before and after photos to show results.

I bought this when I had a severe algal bloom that nothing was getting rid of (water changes, environment changes, blocking out light, reducing light, etc). With this as my last option, I purchased because it was cheap and I had nothing left to lose. There's really no... instructions on a proper way to use this aside from the amount. I was worried about just dropping the tablets into my tank (didn't want my fish to peck at them as they fizzed) so I saw reviews saying to take a cup of water from the aquarium, place the tabs in there and let dissolve and then add the water back and that's what I did. After the first week I didn't notice much of a change at all and decided to try another dose once it was safe to. After /another/ week there was still no change and I thought it was a dud. Then slowly but surely I noticed the water getting clearer. The plants not being covered in algae - the decorations a completely different color because for ONCE they weren't coating in a layer of algal slime. Fast forward 3 months later? My tank is still SPOTLESS. There isn't a speck of algae in this tank, the aquarium pebbles are shiny and colorful like they're brand new, my decorations are like brand new. I haven't had to add more tablets or anything. So - despite the fact I thought for sure this was useless, it's actually been a saving grace and the best choice I could have made for my tank. I had five fish (2 dalmatian mollies and 3 skirt tetras, one of which is 7 years old) and not a single one got sick or died or showed any irritation from this product either. If your tank is a mess of algae, give this a shot and be patient.

This stuff really does an excellent job of helping me clean up my tank. I've posted pros & cons below to help make your decision simple. Pros 1) It's cheap 2) It makes my tank look great, and does a good job of getting rid of algae 3) It doesn't change the color of my water Cons 1) I don't like that you have to remove the carbon filtration 2) I wish there were more tablets in the box. This box treats 80 gallons of water. Just depends on how much you need 3) I'm not 100% sure of how safe this product is for the fish. This may sound ridiculous, because my fish look fine, but I wonder if this increases their likelihood of getting cancer, or other diseases long term. The box does say the product is a known carcinogen to the state of California. And there are a bunch of scary warnings on the back about how it's illegal to use it for any other purposes than as described on the packaging. I guess they don't want you to poison people with it? It hasn't killed any of my fish though. Other helpful info: Usually takes a week before the full effect kicks in. Also, only seems to clear my aquarium for a month or two. Guess if you leave the lights on too long, the algae always is gonna find it's way back. Overall, when I'm looking to rid my aquarium of algae, this is my go to product. I highly recommend this product, and hope you'll be happy with it just as I have.

It didn’t get rid of more string/hair algae types but it definitely got rid of the consistent algae on the walls of my tank. None of my fish have died from this and I use one tablet per month for my 20g.

Amazing result! I was surprised my local pet store did not know of this product. I highly reccomend it.

This product will kill algae AND any plants and snails in the aquarium. You will find this is very small print on the back of the package. I am disappointed that TETRA doesn't make this very clear on the front of the product in large print. They are a reputable company in the industry and should know better .

Broke one tablet into 4 pieces and scattered through myb20 gallon tank putting one pice in my hang back filter did a 24hour black out and it worked like a dream. I've been fighting an algea bloom for almost 2 weeks with water changes cutting back on food and blackout periods nothing worked until I tried this. My tank is crystal clear after a day and a half.

Killed my girl!!! I had her for about 8 years and I loved her like you wouldn't believe. Crazy how she followed me everywhere and would sit in her tank right next to me as I sat in my recliner. She was so full of life and was the most happiest fish! She gave this family so much joy until I tried this garbage after a worker at a family owned well know pet store highly recommended it. I hesitated as I do with everything because I'm extremely cautious especially with change and chemicals that I've never used. I didn't use right away due to the fact that I was still very hesitant. I finally did it weeks later after I purchased it and did everything exactly as prescribed. A couple weeks later she had developed parasites and had turned white and was itchy. She stayed in one spot hidden and wouldn't move. Mind you she is one tough cookie but this stuff was stronger than her this time. Watching her fighting for her life killed me and upset our whole family. Two days later after noticing her acting differently and not looking well she lost her fight. DO NOT KILL YOUR SCALED FAMILY! DON'T USE THIS KILLER! If you struggle with algae use SEACHEM PHOSGUARD! What I would give to have just stuck with that with our stubborn continuous algae (diatoms). Anyhow, past that.. this stuff did absolutely nothing for the algae. It makes your aquarium water cloudy too. Accuclear doesn't ever clear up the cloudiness. I'm wondering now if this is a reason why stores took this off of the shelves. That thought crossed my mind many times and I would normally go with my gut instinct but for some reason I didn't this time. She was a very happy healthy Blood Parrot Cichlid that should still be that today and not dead.
