Use this on all my tanks. Looks so clear, like there's no water in them. Helps with all the gunk break down and go in the filters as well. I buy this in cases.

After months of dealing with cloudy water, I decided to give Fritz Crystal Clear a try. My only regret is not trying it sooner. It cleared up the water quickly and I can finally enjoy my aquarium again.

I hate having to use a clarifier but when you use city water sometimes it's necessary. This product works very well.

Started using the clarifier and in a week I have pretty much crystal clear water. Started off with green to brownish with dirted tank and after parameters got stable the clarifier just made it pop clear. So far awesome product.

I was skeptical about this. 2 days later water was clearer! I highly recommend this product. Even with frequent water changes my water would not be so clear. I decided to use this, it really improved the clarity of my water.

It immediately clouded up my tank and 6 hours later it's still just as cloudy as ever. Fish all seem fine but the tank looks like ****. Picture is several hours later. Looks 10x worse than before I added it.

Great stuff got really quick in mail added as soon as I got within 3hrs water was clear thank you cory I'll be buying more when needed I recommend 100%

New tank and after adding a few bags of eco dirt I had a zero visibility mud pit. Added a couple of charcoal bags to the hang on back and used 6 caps worth (60 gallon tank) morning and night for three days. Crystal clear after that point and haven’t had to use it again. Next time I stir things up it’ll be my go-to treatment. I would however go with the recommendations listed on the description, I just did it my way.

After 2 doses in a 5 gallon tank, the product worked perfectly. I am a very happy customer.

Buying more soon

Amazing product!!!

Did the trick.

I was skeptical to say the least. My water was grungy green for several weeks so I figured, what the heck, I might as well give it a try. I poured 2 cap fulls into my 20 gallon tank about 2 pm. 2 more cap fulls at 8 pm. When I got up next morning, I was stunned to see how clear my tank was! Amazing. Didn't hurt the fish either.

This product does good

This stuff really works. I have tried others and they wouldn’t clear the water at all. After I put this in maybe a couple hours and it’s cleared my tanks. I highly recommend it.

Was not sure about this product.
But a few hours later my tank was clear.

Put the recommended amount in my fish tank. And a couple days it cleared up.

After a few weeks in a new tank, the water in my 10-gallon aquarium got that London Fog that simply would.not.go.away. I tried doing 25% water changes, gravel cleaner, additional filtration - nothing seemed to do the job. This stuff just WORKS and its very easy to use. No negative effect on my fish. Definitely give this a try if your water is cloudy - I used it 1x a day at first as a test, then upped to 2x a day. I noticed a difference within one day, and everything was clear in about 4 days.

I made every noob mistake you could make with a new 75 gallon tank until you couldn't see 2 inches into the tank for the algae bloom. Fish? Where's the fish? I don't see fish . . . .
I took care of lowering the amount of time the lights were on, lowering the brightness, and feeding less. After that I added Fritz Clarifier and waited for 2 days I did a 30% water change and added more Fritz Clarifier, as directed on the bottle, over the next 2 days. It's been about 2.5 weeks now and the water is crystal clear. We added more plants and fish, 23 small community fish now.
I'm very happy, Aquarium Co-op is the best and I'm very grateful to have them as a resource!

I used Fritz Clarifier on a 14 gallon and 10 gallon aquarium. The 14 gallon has live plants, but the 10 gallon only has plant-like decorations. Both have significantly clearer water after treatment. I have treated both tanks 2-times in about 1 week even though the instructions say I can treat every 6 hours I haven't compared this product with competitors, but I can confidently recommend it with my results.

I am so pleased with the results the clarifier caused in my aquarium. I added it one day and the next did a water change, rinsing the pre-filter sponge on my HOB filter and the sponges inside it. “Both” had much more gunk caught in them and it had only been a few days since I’d rinsed them. The clarifier works GREAT at collecting smaller particles, which in turn helps the filter to become more efficient.

Made the water clear and works perfectly in my 20g

Clears tanks without any issues and can be added again after 6 hours if needed (always read the directions).

This really worked as stated. My aquarium is looking good.

Completely satisfied

This stuff has made my tank crystal clear. Love it and highly recommended it.

I had a algae bloom. My tank was greens, cloudy etc.
This is a wonderful product!
My water is crystal clear now!
Great Product made by FRITZ!

Fritz clarifier works great for clarifying a unclear tank. I have used it many times with great success.

Didn't do anything for me. Tank was just slightly Cloudy and product didn't help at all. Maybe it's just me but won't buy again.
