Product description

Size Name:250 ml

Product description

Tetra CrystalWater cleans dirt particles from the aquarium water fast, safely and reliably to help maintain a crystal water effect. It is completely harmless for all aquarium inhabitants and quickly provides crystal clear water. Initially, a white cloud will appear, which is not dangerous and clears away after a few hours. The active ingredients bind small particles in the water into larger ones that can then be filtered from the water by the aquarium filter. For best results the filter should be cleaned regularly.

Box Contains

    I am very pleased with Tetra Crystal Water Clarifier. I use it after aquarium / filter cleans when the water gets rather cloudy. It takes a couple of hours but by the next morning, the water is crystal clear!

    I have a sand like substrate in my planted tank and water changes stir up the fine particals, turning the water in to a sand storm. It does eventually settle but was taking days, with this it seems to only take a single night and back to crystal clear water.

    I was a little bit sceptical about the claims of clearing the fog in the tank but wow, it did exactly that. I wish I had photographed the tank before I used it.

    So first time i have ever used this product did a water change in my tank today and put a few drops of this in my 125 litre tank must say i am very impressed.. for a tank thats just had a 30% water change my water is very clear and most importantly my fish are still happy.. i wont be using it every time i do a water change as i think its better for the tank to just naturally clear the water but will use it once in a while

    Works most of the time, but you seem to need more than the stated amount to really see the difference
