Clarence the Clarifier Fish - 1 pk, Purple - Aquarium Treatment, Clear Cloudy Fresh-Saltwater, Fish-Plant Safe, 10gal Tank Maintenance Each

Love these guys! They work great! Sometimes it does scare me and I think I have a dead fish floating at the top and then I breathe a sigh of relief when I realize, “oh thank goodness, it’s just Clarence.” 😂

This is such a great solution to tank cleanliness. It is a great size so it doesn’t take up much space in the tank and it works so well. It is definitely worth the money!!

This is doing an amazing job at keeping one of my tanks crystal clear. I would say this is not a total fix though. Is your tank already has a bacteria issue I don’t think this will fix it as another of my tanks has a cloudiness issue and this didn’t help it at all

Terrific. Works quickly and continues to improve over time. Usually, our tank water would get a bit cloudy and some small patches of green stuff would start to appear on the walls every 1-2 weeks, despite weekly partial-water changes & cleanings. After 3 Clarences (changing them out every 60 days), the water is perfectly clean at the weekly change, and we can even leave town for almost 2 weeks (the fish have an auto-feeder) and the water is clean when we return. The filters last longer, too - we don't have to change it every month since it now looks clean for much longer. Definitely worth it, and we are buying a bunch more!

Didn't change anything in my fish tank, still cloudy, but looks cute floating in the tank.

We were having such a hard time keeping a couple guppies alive in one tank and a beta alive in the other tank, we tried a ton of different things, even bought the fancy water from the pet store, but we kept losing the fish after a couple of months. We asked multiple pet store employees, they said we might have too harsh of water, even though we kept buying all the balancers and conditioners they kept recommending. We couldn’t figure out what was happening! The pet stores even kept returning the fish and ended up quarantining some of theirs. I bought one of these to try, and my problems were solved! I’ve now purchased at least 4 of them over the last 2 years and I’ve now had the same Beta and 3 neon tetras since I started using it! You can start to tell when the small tank needs a new one since it’ll start to get a little murky. I don’t know how well it does for larger tanks, might need a few, but does great for my 2 smaller tanks

Meh. These have not hurt my fish or nitrate levels, but have not seen a real benefit after 2 months of use. They certainly did not fight against algae blooms nor cloudy water. To be fair, neither did chemical additives (finally had to go the UV light route for the cloudiness that would not resolve with additives/ water changes.) For maintenance on a clear tank, they may help a bit, but I have had more luck with inexpensive filter floss, tbh.

I have to been struggling with cloudiness in my fish tank for 4 years. I clean and maintain my fish tank and filter, I only have 1 fish, so it's not overcrowded. I believe it is the water in the city I live in. I spent hundreds of dollars on water treatments, clarifiers, ect. I bought Clarence, I thought I would try it, desperate for clear water, it worked! After only a few hours,my 10 gallon fish tank, started getting clear! It is now crystal clear! I'm amazed! I recommend this to anyone having problems with cloudy fish aquarium!! It's so cute too!!
