Review: 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!

## Questions & Answers

**Q: Can this be used with seachem prime soultion**
A: do not now !! david mee

**Q: can this clear a green tank ?**
A: This product will not remove the green algae from the tank. It will be better to clean the tank, and then use green away, or algae minus products in the freshly cleaned tank. those products will keep the algae from growing. This product will make the water more clear by combining small contaminating particles in the water and then those gets filtered out.

**Q: Can this be used with an under gravel filter**
A: I have an under gravel filter & use Tetra Crystal Water. Have used it for 3 years without any problem. Hope this helps.

**Q: Will this help with white bits float in my fresh water tropical tank**
A: My not tropical fish sorry can not answer your question.
