Aquarline Hailea Aco-9810 High Output Pond/Aquarium Air Pump, 1800 Liter/Hour

I am currently using this pump to power 17 sponge filters in my fish room, I have had it since Nov 2023 and I'm writing this review April 27,2024. It isn't "super silent" but it is quieter than the several pumps I was running prior to buying this one. Noise level is roughly similar to my husband's gaming PC when all the fans are running. If you're sensitive, you'll hear it, but plumbing it through a closet door would make it nearly silent, and let's face it, it's probably better than what you have going right now.It does its job well, and I personally think it is the best option if you have more than 5, but less than 30 air-driven devices to run. There are better pumps for larger applications, but you can't really force them down to a smaller application without damaging them. For the price, and what you're getting, you can't go wrong with the Hailea.Toss the hose and manifold it comes with immediately, both are useless and crappy quality. Either get yourself a stainless steel manifold with 12-16 outlets, or build one out of PVC and individual air outlets. This will save you a lot of headaches and time trying to figure out where tf it's leaking from, trust me.All things considered, it's a great pump for a great price, for a very specific application.
