I love all the things people are scared of in this hobby..... Definitely love when people are afraid of sunlight (cuz the ocean has LEDS, T5s and MH over it right? lol).............
My tank is inwall on the main level directly across from a large bay window (bigger then my 180g lol) that lets plenty of light in to the fact that it gets enough light my fish wake up when the light starts getting in the tank and stay awake until my t5's go off at 1:30am
I also have a window in the room that lights my 30g cube thats empty but it gives it enough light that the coraline algea has stayed alive for well over a month without any other lighting.....
None of my tanks have algea problems......
I have less then 10 snails, less then 5 crabs, 1 urchin and 1 cleaner shrimp..... I have 14 or 15 fish (5 of which are 4-6" atleast), I feed 2-3 times a day (and dont know how many my wife feeds when she feels like watching the fish eat, but its random and whenever she feels like, not generally consistant.... I dont think anyways lol).... oh yeah and I run a prism pro
HOB skimmer on my 180g that has the 30g tied in w/ a 100g rubbermaid sump. Did I mention I use tap water? LOL
Oh yeah, and I have 2 dogs, and one sheds uncontrollably
