Review on 🐟 AQQA Fluidized Moving Bed Filter with Bubble Bio Media, Air Stone for Enhanced Oxygenation, Submersible Sponge Filter – Ideal for Marine and Freshwater Aquariums Cleaning by Monica Hall

Great offer for a guesthouse with bacteria! Make sure you understand this is not a polishing filter for your water. If you've done a little research on keeping fish, it's for beneficial bacteria growth/property placement lol. I put it on a dual outlet aquaculture pump and put a splitter on top to feed both to the same air inlet. It only took about 1 minute for the air to pass through to catch the rhythm. Works as advertised! Don't expect bacteria to grow on it right away. These things take time!
