Premium liquid filter medium

Effectively breaks down leftover food, ammonium, and nitrite through biological processes.

Offers a settling area for beneficial purification bacteria, fostering a living environment that is biologically active.

In aquarium water, hazardous substances like ammonium and nitrite are constantly generated. With sera bio nitrivec, a product of sera biotechnology, you'll find millions of purification bacteria that help establish a stable biological balance quickly and reliably, ensuring that these toxic substances are continuously broken down.

The added mineral volcanic rock efficiently removes pollutants, binds cloudiness, and provides an ideal settling area for the purification bacteria. This results in healthy, clear, and biologically active water.

When used alongside sera aquatan, you can introduce fish just 24 hours after application!

TOO SMALL
Size: Medium, Color: Blue
Nice socks, but they are way too small. Says they fit size 6 - 10. I kept 3 ( I wear size 8) and gave 3 to my daughter (size 8.5). We both agreed that they were just too small.
