I get into a lot of discussions with new reefkeepers. Something that comes up regularly is "what advice can you give that most people don't think about?" My answer is accuracy in measuring and timing. It makes a huge difference in so many aspects of what we do in this hobby. For all the money spent on our tanks, it pains me to see counting capfuls. Lab grade measuring equipment is inexpensive on Amazon and lasts a lifetime. Egg timers can be found at almost every dollar store in the nation. Anyone with children that buys meds with the little portion cup needs to save those. It costs very little to be accurate and I promise your reef will thank you
