Ok perfect thank you, I'm still gpjng through a protein skimmer either in it or on the back of the tank. I just wanted to avoid the different chambers so I figured I'd just make one huge refugium LOLWill be fine that's what I have just larger took 90 gravity fed to 40 the to sump have pods like crazy and best filtration you can get.
Thank you
With the new skimmers on the market now I would go by that trend anymore. That saying has been around far too long, it started back with air driven skimmers and for good reason. You would get a unit that was 2 to 3 inches round and 18 to 20 inches long and labeled for a 120 gal tank. A good example for not going too much larger is the Vertex Omega 150 there are many using it on 200 + gal systems with no problems. I had a Bubble Magus Curve 9 on a 110 gal and it was way too big for it with a heavy load, it would stop skimming for days at a time and then start again for a day and then stop and so on. You want one that will be consistent with foam production and it will keep levels more stable. As for a refugium rule of thumb would be 1/2 the size of display or larger, anything smaller is really not worth the time, as small refugiums can actually become a problem as detritus starts to settle in it and it is not big enough to hold the amount of plant life and can become a major nutrient source, so starts to become what you are trying to fight. Even Julian Sprung who loves refugiums admits almost all his are about the same size as his displays. Gives you a good reason to start another 90 gal and call it the Mangrove zone, would have 2 beautiful tanks.
