Tetra No More Algae Tablets, 8 tablets, Controls Algae in Aquariums

I’ve been using this for a couple years really helps control the algae in my tank.

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 wiped out a brown algae bloom that seemingly came out of nowhere in my freshwater aquarium. One treatment and the algae was clearing up well the next day in my 5 gallon aquarium. It is safe to use and did not harm any of my fish. Very effective, I would buy these again.

Worked better than the liquid algae removers.

Really good clears out all the algae from my tank.

Dissappointed with results

I am surprised by how well this works! I kept getting brown algae that I had to scrape off the inside of the tank. This stopped it from coming back.

This product killed my Betta within literal minutes of being added to the tank. He started to flail and almost try to jump out of the tank, which he has never once done before. Died within 3-4 minutes. I used half a tablet since I have a 5 gallon tank. I’m devastated, that was my little buddy and he was so beautiful. Have had him a long time and had zero health issues. Now after reading more reviews I see this has killed a lot of people’s fish, I wish I would’ve read closer.
