Every tank needs a differant weapon but the succes is when we all find that weapon and stick to a dedicated schedule, and not slacking off, All my problems were in the first 2 years of discovery and trying new things, now I have a strick schedule of biweekly 40 gallon water changes, one teaspoon of baking soda every night, feed fish daily and kick the skimmer to restart it after power outages. all corals are growing and gettign traded fish are fine and clowns breeding, 2 fatalities in past 2.5 years when they went A-Wall.
