Description
Designed and constrcuted with quality materials, multilayer principle and the largest surface area possible with no clogging.
Sponge material is easy to clean.
Filters are diesnged and contructed for quiet operation.
Air diffusion chamber produces minute and large number of air bubbles which increases the oxygen solubility in water.
Take Note:
Before using, soak the sponge in the aquarium water for five minutes to increase nitrobacterias formation.
Rise/clean the sponge using aquarium water instead of hot/warm water.
Xinyou Tube Bio Sponge Filters (XY-2820 Series) Explained
This Xinyou tube-style series stacks foam around a central uplift so water is drawn through a large surface area with little risk of clogging. We recommend the tube format for keepers who want serious biological capacity without a powered canister: the multi-layer sponge gives beneficial bacteria plenty of real estate, while the air-diffusion chamber throws out a steady column of fine and coarse bubbles. That dual action filters and aerates from a single quiet unit.
In Singapore, the oxygen boost is genuinely useful given our warm ambient water, and the air-driven design sips power and keeps running on a battery air pump during the brief outages our monsoon storms sometimes cause. As the instructions note, soak the sponge in tank water before first use so it settles and seeds faster. Clean by squeezing in old tank water, never under the tap, to preserve your bacterial colony.
