Laguna BioMax, 350-Gram

I HAVE BEEN USING THIS MEDIA FOR SEVERAL MONTHS NOW. MY 500 GALLON FISH POND HAS STAYED SPARKLING CLEAN & I LIKE THAT THE BIOMAX HAS BENEFICIAL BACTERIA IN IT. IT'S VERY EASY TO CLEAN & MAINTAIN & DOESN'T HAVE TO BE REPLACED OFTEN. PRICE WAS BY FAR THE BEST ON AMAZON AND SHIPPING WAS VERY PROMPT.

They worked very well helped keep my pond clear I also use the mini Bio-Max. I recommend them will be purchasing again next season.

I use these in my waterfall pond and they seem to work well. as some one else stated the picture is not right This is about 30 sphere's in it, the part number is correct PT560 not THE PICTURE

Love this product - it helps keep our fishpond water clean & clear. In the future, I'll alternate regular & mini sizes to make it easier to know what to rotate out.

The photo shown with this product says 120 spheres. It is not a photo of the actual box. I was expecting 120 filter pieces. What I received was a very small box with about 30 cylinders--not nearly enough for my pond filter. The weight description is correct. Based on the cost for this small number of cylinders, I would not order them again.

it is okay works well, no special issues

Biomax biological filter media seems to work well. The pond has become clearer since I placed them in my filter. So, very happy with results.

Bought this to use with my PowerFlo Biological Add-on Filter Chamber.Good quality,price and service.,
