Rated 5 out of 5 by Citroen6 YES 5 stars!
I honestly don't understand the reviewer DOESN'T WORK of 1 star. I have tried other water clarifiers such as TopFin, and Tetra with poor results. However these NatGeo Water Clarifier tablets do the trick. Yes its true the water will cloud up but thats for no more than 24 to 48 hours then it cleans up water "big time", I would say 90% better. I have a 40 gal and 2 - 20 gal fresh water aquariums. maybe if this product came with good clear instructions it might help. Since the product works by "clumping" to dirt in the aquarium I clean the filters after 24 hours and put them back in. I am not sure if this product can be repeated, again no clear instructions or helpful use tips BUT it does work.

Rated 1 out of 5 by andrea2011 does not work
If I could give this item lower then a 1 star I would. I have 2 fish tanks (a 20 gallon and a 5 gallon). when I put this in either of my tanks nothing happens and I end up having to fish the tablets out of the water. It actually clouds up my 5 gallon tank (even though I only put 1/2 a tablet or less in the tank). the packages says they are fast dissolving but the do not work.
