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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by K***E on 27 February 2026* Quick delivery good product would use again ### ⭐⭐⭐⭐⭐ Highly recommended *by S***C on 9 December 2014* This product does what it says on the tin and is amazing.
