Review on 🐠 Flexzion Aquarium Canister Filter - High-Performance External Filter for 150 Gallon Fish Tanks by Kelly Johnston

I ordered this a few months ago and didn't open the box by the return date. This was a different, lower level version of what was being sold. It didn't have an on/off switch (you have to unplug it) and the main reason I bought it - the UV lamp - wasn't on either. I stuck with it anyway, so after deciding to make the best of it, I started using it. It quickly started making an absolutely insane noise. I disassembled it, cleaned and oiled the post a few times, deflated and guess what? Loud noise. This is a bit louder than my previous, small pump in the tank, which had no soundproofing and only cost 5€. What a waste.
