I've had my tank running for about 2 years, maybe 2 1/2. I can't believe it but only until recently, and I've only heard it maybe three times in the last few months, I've heard the dreaded clicking sound. At first i didn't think anything about it. It sounded like a pump or something metallic. I've had very little problems with the tank. Also, I haven't added any rock in over 2 years. No fish ever lost. A snail or two dies rarely, I assume from natural causes...knocked over by fish, and can't right himself...the like. I have had the same cleaner shrimp in the tank for nearly two years. Corals are all fine. Is this something I should be concerned about? As of right now, I'm thinking, if it hasn't done any harm I'm not going to worry about it...Thoughts?
