Overview
On the ceramic body, there are millions of tiny holes, which serve as a habitat for many beneficial microorganisms to improve and maintain good water quality. Good quality ceramics are durable, "absorb well," and easy to clean. Used for overflow filters, rain bars,… With good absorption capacity, the small holes inside will become a refuge for beneficial bacteria.
Combo gear is commonly used for freshwater planted tanks, nano aquascapes, and routine maintenance — always match capacity to your tank volume and livestock.
