Interesting comment, I have never considered it a Zeo System. My LFS recommended the AA & CV, liked it so gradually added more Zeo products. I have not read up on what a "full" Zeo System includes. what defines a "full" System?
I do NOT have a refugium and only use a Deltec HOBO skimmer (MC600). Despite using many of the Zeo products I never considered my system as ULN as
I feed way too much (with no apparent ill effects). I feed 3 to 6 cubes (blister pack) of Kikari Brine shrimp
per day for 6 fish (4" Purple tang, Flame angle, 2 Black Ocellaris, Yellow Coris wrasse, & a Royal Gramma). The rest of the fish feed on naturally occurring pods (2 Spotted Mandarins, 2 Banded Pipefish, Dragon Pipefish & a Bluestripe Pipefish). For the corals I feed 1/5 teaspoon of ReefRoids and 1/5 teaspoon of ProReef powdered phyto
Twice a day (noon & after lights out). During the daily daytime feeding I also add 1/2 cube of Cyclop Eeze per day. In addition to the daily feedings, once a week, sometimes
twice a week, I spot feed my carnivorous corals approximately
8 to 12 cubes of brine shrimp. I mix this up with Krill & PEMysis. I would never recommend my feeding schedule to any one. I can hardly believe that the system has not crashed. No outbreaks of algae or cyano so I keep pushing the bubble to ensure our corals are happy. I do get algae build up on by frag plugs. These I scrub & scrape off weekly. On the plus side, I have a super overstock of corals and I try to do a 27 gal water change, 19% of our140 gal tank, once a week. Realistically it is more like every two weeks as I semi regularly do not get to it weekly. I have stopped testing for Nitrates & Phosphate, as in the past they were always acceptable. I do have a sock of Phosban in the Deltec MC600.
Allmost, with such an intense feeding scheduled do still think it is a Zeo ULN System??
Just a note, the tank does react to high nutrition levels. I had a beautiful 8" Desjardin Saifin Tang. As he matured he started to knock over corals trying to get at algae. The only way to stop him was to feed him a full 12" X 12" sheet of nori a day. As you know what goes in comes out. In no time I had algae everywhere including brow slime algae on the glass & rocks. Unfortunately I had to sell him to save the tank
