Maxspect Nano-Tech Bio-Block 2pc is used as a filter media in freshwater and marine water aquariums to establish bacterial colonies for effective water treatment.

Maxspect Nano-Tech Bio-Block is a new filter media for use in freshwater and marine water aquariums. With an ultra-high surface cross-cutting ratio and filtration area, each Bio-Block has up to 1,080 m² surface area for the establishment of bacterial colonies. With the use of stabilized microbial sewage treatment technology (W-BAF), the Bio-Spheres have a unique advantage in the treatment of water columns with high Ammonia-Nitrogen (NH4-N) and high Nitrate-Nitrogen (NO3-N). The Bio-Block excels at establishing bacterial colonies in the form of Bio-Nano Composite Films, it allows different species of bacteria and fungi to grow on its large surface area, such as nitrifying bacteria (including species of the genera Nitrosomas, Nitrosococcus, Nitrobacter and Nitrococcus), yeast phototrophic prokaryotes, etc.

Great for walking all day at work as well
Size: X-Large, Color: (001) Black / Black / White
I walk approximately 10 miles a day at work, in a manufacturing setting. On concrete with steel toe shoes. My feet have been begging me to change from the socks that I have worn for years. I have worn these other name brand socks for probably 10 years. So, change was obviously something I had to be pushed into. I got on Amazon and searched for training socks. I read the description. Glanced at the reviews. I decided to move forward with purchasing these. I could not have been happier. My feet began feeling better immediately. And the priced was very reasonible.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!
