How many gallons does "Tetra No More Algae" treat? On the description it says 160 gallons, but on the box is shows 80 gallons? Thanks
Answer by ChewyMay 28, 2018
This supplement treats up to 80 gallon tanks. The box contains 8 tablets. It's recommended to use 1 tablet per 10 gallons of water.

Has anyone here used this product while your fish was in the tank?I need to know, my fish love clean water and it needs to be clean again.ty
Answer by ChewyJul 07, 2017
You can use this product while your fish are in the aquarium. Be sure to follow dosing instructions carefully to ensure the active ingredients are not too concentrated for the volume of water.

Will this affect loaches or snails? Thank you in advance...
Answer by ChewyMar 01, 2018
We recommend that you remove them from the tank while treating. You can return them to the tank after you have finished the last dose, completed a 25% water change and have left the new carbon filter cartridge in your filter for at least 8-12 hours.

You said to use it with the water but remove charcoal during use. how long should you wait to put charcoal back in filter?? confused?
Answer by ChewyJul 24, 2019
The carbon filter and charcoal can be returned after 6-8 hours.

Turtle Tank Must Have

I keep my turtle tank outside. During the morning and afternoon the sun shines on my turtle tank causing algae to grow like crazy. After two days the tank is dark green with algae. I tried many anti-algae products, but none would work. Finally I tried a tablet of No More Algae after cleaning my tank water and it worked! I added one tablet for three days and the water stayed super clear for at least 3 weeks!! It had no effect on my turtle or the fish I feed her. It even cleared up the filter! Definitely 5 Stars and will continue to use this product forever!

Awesome product

We used this for our 55 gallon tank and it was magic. Cleared up the fogginess right away. We change filters quite often but this tablet helped make the tank prestine.

No more algae

I previously had No More Algae from another company name. I’m not sure if Tetra brand is going to work as well yet, but if the ingredients are the same it should. The previous brand worked wonderful and I was surprised. I use them in my fish tank and in the little pond that I have on my deck. I hope that they are the same it is wonderful not having to empty the tanks and clean them.

Nope nope nope

This didn't work at all, did not remove any algae. In fact, within 2 days of taking the filter out and putting the tablet in there is even MORE algae in the tank. The instructions also don't even say how long to keep a filter out or how often the tablets can be used. So, no to this product. Do not recommend.

Works great

I love these tablets! I used to have to clean algae off the walls of my tank and accessories every week. Now, there's never any algae on the walls and a minimal amount on the plants and rocks. I only use half a tablet each week since I have a 5-gallon tank, and I appreciate that the tablets are super easy to break in half (meaning they don't crumble all over the place). I just pop half a tablet in each week and they've helped so much with algae. I will continue using these! I haven't noticed any adverse effects in my fish's behavior or health.

Wrong stuff

I could not even use this stuff to try it. I have live plants and it says not to use with live plants. It also would have taken the whole box to treat my tank. So I cannot recommend or recommend this product.

It works better than expected

Not only did this product prevent algae growth it cleared up already existing problems. It worked for more than a month before I needed to use it again.

Success At Last

This is a great product! I've used many other algae control products and none have worked as good as this one. It took all the algae off the rocks and plants. The best part is that I don't have to use it again for at least a month. I don't like putting a foreign product into the aquarium unless absolutely necessary and worry about its long term affect on the fish. Therefore, once per month is tolerable.
