I have a Reef Octopus Classic 90 HOB skimmer I want to mod. I want to add a 3/4" tee between the elbows on the intake pipe (see arrow in pic) for my bio-pellet reactor's output. I've heard these chinese skimmers use metric thread fittings. Is the pipe on this skimmer a metric diameter (if there is such a thing) or is it standard 3/4" pipe?
TIA, Shawn
