An inquiry from Oz.
I've just discovered this site, having also just read Don Carner's articles. I've read the whole thread. I have a 150-gallon system, with a small fish load and a heavy coral load.
I'm intending to build a unit that is about 40 inches high and a diameter of four inches. I intend to wind the coil around an inner tube about 3 inches dia. This will fit inside the larger chamber, and the end of the coil will discharge inside the inner chamber containing the media.
I'm a little confused about the internal diameter of the coil tube and its length . Don recommends one-quarter of an inch to three-eights of an inch ID.
If I use one-quarter inch ID, how long should the coil be?
How long should it be if it's three-eights inch ID?
I'm happy to make it as long as necessary to ensure the water entering the media is oxygen-free. I'll be able to continue to coil the tube, as it will fit inside the void between the inner and outer chambers.
Hope you can advise me.
