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.

Hola si funciona yo eche un tapón entero por qué desde que me mudé no sé por qué el agua aún que sifone el acuario y tenga sus filtros y eso se me ponía muy turbia el agua incluso con mal olor y olía toda la casa fue echar esto y al día siguiente mire y mira no os asustéis por el nivel del agua es que como hace tanta calor aquí compré por Amazon un ventilador para el acuario funciona perfectamente pero evapora el agua muy rápido
