SeachemClarity, 250ml (8.45 Fl Oz)

I used this to clear up cloudy water due to adding sand substrate to a new reef aquarium. Works perfectly!

This works rapidly and does a really great job for cloudy water.

I put some driftwood in my 75gal and it quickly covered in biofilm. The water looked “dusty” so I tried this after reading the dust was tiny bacteria or algae. It was a little cloudy after using it, but I woke up to my tank being crystal clear. It’s blowing my mind, honestly. Great product!

used this to get some detritus out of suspension during setup. would not use on any aquarium with a filter requiring effort to change, or where the physical filtration is intense. i cant tell how much it helped, but it definetly did SOMEthing

Excellent product

Does a great job at collecting the little particles to be sucked up by the filter, keeps water crystal, good for the price

This is an excellent product and works exactly as described. I had some residual cloudiness in my Mbuna tank and from some aquarium sand. After two uses this product completely cleared up the water. And it is crystal clear. You need fine filter floss to use this product correctly. After using it you will see a large amount of orange debris in your filter floss. Repeat as needed, but only takes one or two uses. Highly recommend this product.As the label states you will see an initial haze, but it clears up after two hours and stays clear.

Clears the tank but fills the filter over and over with brown residue
