Description
Biological Filter Media 7 in 1 can be identified as ceramic tubes approximately half an inch. The product primarily provides mechanical filtration, effectively acting as a sieve to trap particles of waste. Bio Filter Media should be used in the second stage of the filtration. The irregular arrangement within the filter basket creates eddies of water which disperses in many paths creating an even flow of water for subsequent media layers.
Bio Filter Media are also porous and after prolonged use, they will provide substantial surface area for bacterial colonization. This product is a useful source of “back up” bacteria.
1) Replace media when it breaks / crumbles or when it is clogged up with dirt.
2) Never replace all this material at once, you will be destroying valuable denitrifying bacteria. Suggested is to replace half and mix with old half.
