These had me on the fence since there were very few reviews and some were negative. The price was worth the try and I must say it was an amazing investment!! It's best that you don't use chemicals to make your water clear. These are all natural which is the best way to go. It took no time for these to work and my water is very clear!
It works & its not a gimmick!

I have a 3 gallon tank that kept getting cloudy. Water changes didn't work, I used water clarify products that didn't work. I gave this a shot thinking it wouldn't work. It took 10 days but it was worth it to finally wake up one day to a clear tank!

The package was the exact product we were looking for. They were smaller than expected, but are perfect for our tank

Have had these in my tanks for years..as they help with the water clarity. think they are worth the investment and they last long enough that they are budget friendly over the long life of the product.

I have a 29 gallon tank with a Cory catfish and a Huge plecostomus that was really getting funky. Despite using liquid chemicals that are designed to solve the problem, as well as partial and even complete water changes, it would get smelly soon after. I put 4 of these blocks in as a last ditch effort and I can finally walk past my tank without having to hold my breath.
