API Bio-Chem Stars

API Bio-Chem Stars is used to provide a home for growing nitrifying bacteria that convert harmful ammonia into nitrate, helping to establish and maintain a healthy aquatic ecosystem in fresh or saltwater aquariums.

API® BIO-CHEM STARS biological media provides a home for growing massive colonies of nitrifying bacteria to establish and maintain a healthy aquatic ecosystem. The nitrifying bacteria convert harmful ammonia into nitrate. This is called the nitrogen cycle, and it occurs naturally in all underwater environments. Your fish will produce waste, which fuels the growth of the beneficial bacteria that will comprise your “biological filter”. These bacteria continue to grow as your aquarium ages – living on the top layers of the aquarium gravel, or in filter media such as API BIO-CHEM STARS biological media.

Formed under a patented production process that creates a 50-70 micron internal pore network. This pore size is optimal for the growth of beneficial, nitrifying bacteria that remove toxic ammonia and nitrite. Space-age porous polymer allows for rapid transfer of oxygen and water which keeps bacterial colonies healthy and active. Due to their design, API BIO-CHEM STARS biological media achieve 4 times more surface area to colonize bacteria than ceramic rings.

Instructions
Rinse thoroughly to remove any dust. Place BIO-CHEM STARS biological media in the last compartment of your filter. BIO-CHEM STARS biological media will become colonized by bacteria within several weeks.

Well thought out and easy to install
Color: 2-Pack Black, Color: 2-Pack Black
Definitely organizes and maximizes cabinet space for spice storage. It’s a little rickety. If you are using glass spice jars you will likely need to use the included screws into the cabinet because the double face tape it comes with might not hold up. It might work with the plastic spice containers, but even then it seems like it would not be sturdy enough to hold the weight. The instructions were clear and it installed quickly. If it lasts, it was definitely a value upgrade in my cabinet.

Don't buy the other brands
Color: 2-Pack Black
I'd give these a 10 if I could. I bought another version but returned ii because I didn't think it was very sturdy. These were only $8 more and what a difference. They are a very well made and a lot more sturdy. The extra $8 was a real bargain and well worth it.

Great for short people to see and retrieve spices from upper shelf! Holds a lot of weight easily!
Color: 2-Pack Black
These spice racks were very easy to install in my cabinets. Actually, I have only used the adhesive, and they are holding all of the weight of the spices without any issue! These are remarkably heavy duty. I am short (5"3") and most of the second shelf is not really very useable without a stool. I can pull these out and turn the racks making all of them visible and easy to reach! I have two and I'm seriously considering ordering more! It makes organizing a breeze too!
