Tetra Usa Inc. No More Algae Tablets - 77344 | Removes Existing Algae & Controls New Algae From Forming, For Glass & Acrylic Freshwater Fish Tanks, Use Once Per Month

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.

We have a well established 3.5 year old freshwater 10 gallon fish tank. We didn't have any algae problems until we went away on vacation and I used these feeding tablets. So even though I thoroughly have cleaned the tank every few months, the brownish orangey algae still comes back. I didn't want to use chemicals that could harm the fish but was desperate - who wants to look at a dirty fish tank (note water was clear, this algae would form along walls of tank and on the bottom). Anyway, I have 4 neon tetras, a snail, platy, 2 cory catfish. I did not want them to die so I took the following precautions: removed snail and kept him in a separate cup during the cleaning process, did a 25% water change and removed carbon filter, wiped the sides of the tank with a cloth carefully to remove what I could, got a cup of the tank water, added the tablet, mixed it up and added to the tank. I let this do its work for almost 12 hours (just wanted to be sure it really had a chance to work), added a fresh carbon filter, let that cycle overnight, and then I added my snail back. I monitored the fish for any signs that they were not tolerating the chemicals. They all looked fine throughout. The tank was clear of algae by the time I was done and seems to be getting better every day. This stuff is a miracle and I plan to do this every 2 months or so to keep it up or perhaps as needed if I see it come back. None of my fish were harmed and my fish tank looks great - 5 stars for this stuff!!! You must follow instructions carefully for it to work and for the protection of your fish/snails...

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.

Works pretty good. I buy it monthly.
