Maximize Biological Filtration Efficiency

The original sera siporax Professional is designed for both freshwater and saltwater aquariums, as well as ponds. Regardless of the filter type (internal, external, or trickle), it optimizes the surface area necessary for biological filtration and provides an ideal substrate for the establishment of essential filter bacteria. The filtration and decomposition processes that occur at the bottom of natural bodies of water are crucial. Micro-organisms process organic waste, making it accessible as nutrients for aquatic plants, while effectively removing pollutants like ammonium, nitrite, and nitrate. In nature, minimal waste is generated per volume of water, allowing for sufficient micro-organism populations on the existing substrate. However, an aquarium is a compact ecosystem, making it essential to maximize the settling area to ensure complete and safe breakdown of organic residues. sera has achieved this with their innovative high-performance filter medium, sera siporax.

Unlike other filter rings on the market, sera siporax is made from sintered glass. This unique material features a distinctive three-dimensional pore structure that significantly increases the surface area. Additionally, the fine pores create the perfect conditions for bacteria to thrive and decompose pollutants. Since it operates as an interconnected system, the bacteria are continuously flushed by water, enabling them to break down contaminants with optimal efficiency. Moreover, the exceptional pore configuration facilitates self-cleaning of the substrate, resulting in extended filter lifespan.

Perfect trimmer for my yard.
Style: 20V String Trimmer Kit
Works great. Love all the features for the price. I can get two yard trims out of 1 battery charge which is fine for me.

Nice unit, but poor user's manual
Style: 20V String Trimmer Kit
The unit itself is very nice. Seems sturdily built and is lightweight. Adjustable length works well and locks securely. I question the need for two speed control, but their claim is the lower speed saves battery power. I am not sure how much of a difference it makes and changing speeds in use is not very intuitive. A better choice would be an in between speed which is permanent to get better cutting and a little longer battery life. My annoyance comes from the lack of much information about the "automatic line feed" and how it operates. The fact is, the user's manual is bare bones for user information. The booklet is small, is divided into three languages, and all of the "icon" diagrams to explain things are so small you need a magnifying glass. I wanted to know what triggers the line feed, how it knows to lengthen it, and how it knows to stop feeding. None of that information is in the book or on the Black and Decker website videos. Aside from that, the unit is built well and should be durable. It is a good value for the money.

Light weight and easy to handle
Style: 20V String Trimmer Kit
This is my second one. Light weight and easy for me (old woman) to handle. Unit rotates so you can edge. The old one lasted right at 6 years. My old batteries work on new unit also. I get the one with the wheel which makes it much easier to edge. This one auto feeds and my old one didn’t. I don’t know how I feel about the auto feed. Another brand I had before with auto feed stopped working. That was a pain to manually feed. Have only used the new one twice
