Nearly Everything Died Over Night

[ramsey]

Hi Justahobby - gosh I didn't think about the water issues. We have purification system in the house and use that for our aquariums - but the main is from saws.

You may want to make sure it's not hooked up to any copper lines (outgoing from the RO unit). Copper's toxic. Also, you may want to buy a cheap TDS meter and check your TDS though this is not likely why things died. If I had to guess, I'd say the tank's not cycled. Let your live rock cure for about a month or two then add a cleanup crew (make sure ammonia, nitrites are 0 and nitrates are low <5ppm, 0 is better). Don't worry about brown stuff on the sand or algae, it will go away and it's actually a good sign. After having your cleanup crew for a few weeks, as long as everything is doing good, add a coral or two. Then a few weeks later, a fish. See what I'm getting at? The slower you go with this hobby, the better. If you don't believe me, look at Justin's signature.

Sorry for your loss though and look at it as a learning experience.
