Ever look back at what you used to do and go OH MY?

For the first eight years of saltwater reefing, I used tap water, mixed my salt up in my sump, never tested the water, and was very lazy about even doing WCs.

I had a lovely tank back then. Of course if something didn't live in it, I just didn't buy that again. Otherwise, I had most of what I wanted and it thrived. Until one day, I came home from dinner to a cloudy tank. Poof - all my corals were GONE! I had done a WC earlier. The only thing I can think of is that I used a different dechlorinator than I usually did and it was a bit dated. That of course led to a cycle and a series of treating a fully stocked tank (Nasa tang, Palani tang, yellow tany, emporer angel, foxface, mature wrasses, bluespot, etc) for secondary issues. Lost all but 1 fish.

That is when I discovered online reef forums. Totally changed what I know and what I do.

So, now that you know my dirty laundry, share your story...
