What types of bio media or what not have you guys used to slow down nitrates?. I know its inevitable of course but im wondering what I can add to help filtration to help slow down the build up.
The Mattenfilter, Hamburg Mattenfilter, or foam sheet filter design dates back to the 1960s in Germany. According to various reports, the filter was invented by aquarists near the city of Hamburg, hence the name “Hamburger Mattenfilter” or “HMF”. While the basic design has changed very little, the parts used today are longer lasting. Reticulated polyurethane foam invented in 1956 made the design possible. http://www.swisstropicals.com/library/mattenfilter/
