Qanvee Double Sponge Filter QS-200A
The high-quality Qanvee sponge filter is one of the best sponge filters on the market. Its bubble maker rarely clogs and can run almost indefinitely without needing maintenance, producing delicate, consistent bubbles. This filter provides excellent mechanical filtration, making it ideal for tanks up to 1.5 feet. Additionally, it allows you to add bio media, increasing the surface area for beneficial bacteria to colonize.
For optimal performance, the sponge should be rinsed and cleaned every three months.
Simply connect it to an air pump, and you're ready to go!
 
Shrimp Mania’s Comments:
I started using these filters based on KW Shrimps' recommendation because I was tired of constantly cleaning cheap sponge filters that clogged too often. Since switching to Qanvee filters, I have never had to clean the bubble maker—they’ve been running for seven months without a single issue. I only clean the sponges every few months, and that’s it! This is hands down the best sponge filter I've used, and I highly recommend it.
