I bought a used Reef Octopus SRO 5000 calcium reactor, and have had issues with it leaking. I replaced all of the push fittings for the 1/4 lines, but it is now leaking out of the lids on both chambers. I tried to google it and find replacement o-rings for each chamber but only found them on one website, but they were out of stock. Has anyone ever had to replace Reef Octopus o-rings and know where I can find them?
