Thanks....I love this question. The answer is yes.....like most people I've had my ups and downs. This tank has been mostly a success but prior tanks were hit and miss. I always had proper flow and lighting but I never could get the proper nutrient level. I think identifying the proper nutrient level in the aquarium is the hardest part and I believe in feeding a decent amount but also in heavy export with the use of a big skimmer, regular water change routine and I also use bio-pellets as an additional biological means. I know in past tanks I either was too nutrient poor or had excess nutrients that hindered coral color and growth. Experience helps me observe and monitor coral health and adjust the nutrient import/export if need be......it is a true balancing act but once you get a good routine that your tank responds too it becomes pretty easy.
Oh and a bit of luck never hurts either.......knock on wood.
