Here’s my 1st attempt. Still needs a little tweaking / drying, and I’m waiting for a new flow meter in the mail, but otherwise, it’s ready to roll when all the other parts dry. Since only 25 gallon, the chamber should hold enough stones. I’ve got enough acrylic to make 2 more, so if this design sucks no problem, and if it’s sweet, then I’ll copy it and use actual power tools to make it nice, as opposed to hacking at plastic with a hand drill / saw.
Used less than $20 of acrylic and an old Mini Jet 404 (18 - 106 gph).

Certainly will, that’s draft #1. Got my flow meter in so will check that out this weekend. Still waiting to hear from my scrap acrylic lady re: 2 3/8″ OD tubing for the inside chamber… I could only find it in 5′ foot tubes, which is totally not necessary - not paying $105.00 for a 5′ foot piece of tube I’ll never use. So I’ll check the flow, and maybe just run the zeolites in a bag inside the tube for now, until I can get a nice piece of scrap 2 3/8″ acrylic….
More updates to come - new clown pair, nice A. soli, an EcoTech Marine Vortech…

So this idea was scrapped. Ended up using another tube sanded down to slide for the inner chamber. Tons of little stones getting stuck in the original design. The new one is, dare I say, flawless when pumping the stones
