Coral Reefer has convinced me to change my current overflow to a herbie with two drains. The question is, my sump is mirror image, so if i drop the drains straight down, I don't think I can fit my skimmer in the first compartment. so, the option would be to have the overflow have a couple turns before entering the sump. The research online discourages any horizontal transitions. Can I get away with a couple 45 degree transitions for about a 16" drop? the herbie pipes will be below the water line in the sump, which gives me a little more clearance. I think what I could do is for the main drain go straight vertical, and the trickle having two 45 degree turns... Thoughts? Also, my stand it too tight to the wall to permanently attach the new return line that will snake up the back of the tank. Any advice as how to secure the line? I'm planning on using braided nylon tubing unless you DIY cats have other ideas.
