About this item

• Dimensions: 2-7/8”R x 3-3/4”H. Max tank size: up to 20 gal.

• Here’s a revised version of each line to convey the same ideas without duplication:
• - A silent filtration system.
• - Particularly effective for raising small fish.
• - Effectively eliminates harmful substances and ensures water remains pristine for your aquatic pets.
• With multi-layer sponge filters, this corner filter combines physical and biochemical filtration for your fish and increases the oxygen solubility. The top layer of white filter pad serves a mechanical filtration, and the black bio-sponge and ceramic rings work as a biochemical filtration and support colonization of beneficial bacteria.
• Easy to maintain. Just take out the sponge and rinse well when it becomes dirty. It's complete set and includes all the filter components - gravel, ceramic, sponge, etc.
