So....new to forum, not to aquarium keeping. Have an amiracle overflow box flowing to a custom twenty gallon long refugium. The white bulkhead in the overflow box has an O-ring inside the acrylic, and one outside. The O-rings have degraded to the point they were splitting and wouldnt seal. We have tried all local hardware stores (lowes, home depot, etc) and cannot find ones that are thick enough. Anyone know of any good source? As far as I know, amiracle is out of bussiness. Not an emergency, but getting alot of dripage, and saltcreep down the flex hose and need to get this fixed soon.
