Aquarium Water Clarifier | Clear Cloudy Fish Tank Water Treatment, Safe for Freshwater & Saltwater Fish and Plants - Purple, 2 Pack

We started by placing Clarence into a a tank in which the water had already become cloudy. It didn't clear up the tank, but the tank did not get worse. After 1 month, I cleaned the aquarium, and placed Clarence into the fresh water.It has been 2 weeks and Clarence has kept the tank clear this whole time. Looking closely I noticed the white balls inside are turning green.Looks like Clarence does the job as advertised. I purchased a second one and put it on subscribe and Save.

Put this in with my fish; fish are still alive and happy. I got the purple fish device; it doesn’t swim. Just floats off to the corner. I’ve had it in for 3 weeks, I do see a massive improvement. 10/10…would recommend.

made absolutely no difference/improvement to water clarity. had it in for a week.

Cute but to soon to tell if it works

I have a BioOrb tank and Clarence has really made a huge difference in clarity. The tank is staying cleaner longer. Love him....teordered.

It may have helped with chemical balance not really sure but I needed over all water clarity and it did not help my tank with that.

Love it

Got this little guy for my daughters goldfish tank. He is now apparently the king of the fish. The water is already much clearer than before and the fish don't mind him at all. I like that I can just plop him in the tank and I'm done. He just floats up top doing his thing. For roughly $6 a month it's one less thing I have to worry about which is great. From one king to another, I'd say he's doing a good job!
