Did you smell anything like rotten eggs - even a faint smell?

If you weren't moving water through your ca reactor, the water in the ca reactor was sitting without oxegyn and would have become anaerobic. This can lead to the production of hydrogen sulfide. If you have water sitting in pipes, you should always flush it so that it doesn't end up in the tank. With a ca reactor, the water moves through it slowly and it's possible you might not have noticed the smell.

Aside from hydrogen sulfide, there are other problems that can arise from anaerobic conditions, but you would have to do some research to see whether the symptoms relate to your experience.

There are some recommended solutions for this and some good documents on the web that can help you through it. I only remember a couple of things such as leaving your lights on, maximizing aeration by pointing powerheads at the surface, putting in new carbon and water changes.

Hope things take a turn for the better. Good luck.
