EmDixie Posted August 8, 2022 Share Posted August 8, 2022 (edited) Hi guys! I'm really struggling with my Linear Air Pump. It's the style recommended by Aquarium Coop though I bought it directly through the manufacturer. It is set up with an overhead loop and has 22-24 current drops which it's definitely rated for. Each drop goes down into a Coop sponge filter with an air stone. The tanks are all about 16" tall as they're 20gal highs and 40gal breeders. The issue is that I can't seem to get air to actually bubble through the air stones once they're placed onto the bottom of the tank. It is so incredibly frustrating. I've tried balancing them and I'm literally out of ideas. I think I've adjusted things enough only to come in the next day for a tank to be completely stagnant. Any insight is very welcome!

Fish Folk Posted August 8, 2022 Share Posted August 8, 2022 Sounds like you could gave a leak. Low pressure. Did you seal / cement your PVC loop together? Do you have many open lines that are not valve-controlled? 1 Link to comment Share on other sites More sharing options...
EmDixie Posted August 8, 2022 Author Share Posted August 8, 2022 All of the overhead PVC is cemented. Every port has a valve. There's 40 (ish) available ports with 22-24 in use. I've checked those not in use and they are not leaking air. I would agree though, it's definitely a low air pressure issue. Link to comment Share on other sites More sharing options...

I would agree though, it's definitely a low air pressure issue Turn off 10 of the valves and get the others to work "well". If you can't then you have a leak somewhere or potentially a situation where the pipe going into your system might be too small. You can hook up two in series if it's a situation where you're not getting enough force. Photos of your pipe / output from the device itself and how you have things setup might help trouble shoot as well. 2 Link to comment Share on other sites More sharing options...
Brandon p Posted August 9, 2022 Share Posted August 9, 2022 I would break out the bottle of soapy water and start spraying from beginning to end to find the leak. 2 Link to comment Share on other sites More sharing options...
