Wow it’s quite! I’ve got it running 25 sponge/Ziss Filters.
I love this pump! It’s super quiet, it’s inside a cabinet in my living room and I barely can tell it’s there. All I hear is the sound of the bubbles popping. I’m running 8 sponge filters and 6 air stones with plenty of pressure and will be able to handle many more tanks as I expand. As always good quality product at very reasonable prices.
It took a while to figure out the the output of the pump had disconnected from the housing, possibly in shipping, but once I got it to work, my 24-outlet manifold probably can get expanded to a 48! Thank you for having a great product available. The rubber elbow that is included barely stretches over 1/2" PVC, so I'll be looking for a coupler to connect the elbow to the PVC. This was not plug and play! I had to watch dozens of videos to figure out how to connect it to my manifold, then once I had it connected, it wasn't blowing, so my husband took the housing off and reconnected the pump to the outflow tube. Please consider offering information on couplers, barbs, hoses, hose clamps.
I like the pump. Its great.... but I can't for the life of me get enough pressure in my loop to run my sponge filters. I had air coming through each line all the way to the bottom of the tanks, but as soon as I plugged them into the sponge filters, the air stopped. Water runs up the air line, and I have zero flow. I've done more research on this than I care to admit, but I just can't figure it out. Every video and article I find makes it sound like plug and play. 6 hours later and I'm stumped.
