Pre-colonized 10 pc 32oz ceramic rings in media bags plus 192oz of nitrifying bacteria om 3.5 gallon pail.
Porous pore structure gives these rings many times more surface area. Optimun surface area supports large bacterial colonies. Does not break down like other media. Speeds nitrification.
The biological ceramic rings may be recharged by cleaning monthly. After cleaning, be sure to re-colonize with Microbe-lift Nite-Out II. For best results change bags every 4-6 months. Use 1 bag for up to 150 gallons of pond water. Test your pond water weekly.
