Highly recommended
This product does what it says on the tin and is amazing. My water was already clear (not cloudy at all) but there was small particles or simply not crystal clear to the highest limit, this product made it crystal clear (water clearness quality now up to the level of a show tank in an aquarium shop). Shrimp safe (at least it was in my tank): No note about its usage in shrimp tanks on the package. I have a mixed fish and shrimp tank (20 mixed red cherry and amano shrimps), had no issue with shrimps after I used the product so I can say t was shrimp safe in my experience. Leave 24 hours between this product and tap water safe (as stated on the package instructions). Highly recommend!

Tetra Crystal Water Clarifier is brilliant.
I received something similar to the Tetra Crystal Water Clarifier in a bio-orb filter pack I ordered once before and it worked a treat on my fish tank making the water very clear and the tank looked very clean. I tried to look for the same product again but was unable to remember what it was called and I had well and truly thrown out the packaging. I am very bad for reading reviews and I usually go on price or a recommendation from a friend or family member. I ordered this product without reading any reviews and was very happy to say that is does exactly what is supposed to do and my fish tank has extremely clear water and looks very clean.

Works great
My water was cloudy for weeks, I replaced the filter, did partial water changed but it still remained a bit cloudy. This stuff was literally my last resort. Luckily for the fish it worked! I did my usual water change today and added some of this to the tank, it's now 6hrs later and for the first time in ages my water is as clear as tap water! Plus the fish are more active. Iv noticed some people complaining about the price, really? A fiver? I'd pay triple that for clean water. Highly recommended
