Justin,

The swingarm is definitely getting replaced...not sure how much of an upgrade, but it will again be calibrated.

API Test kits

Most of the corals are 6" or less from the surface of the water.

No, no skimmer.

Kent Tech M, Tech CB, Strontium and Molybdenum, Essential Elements.

I feed the tank once a week with a cube of Reef Cuisine...I will begin to run with Eric Borneman's (sp) recipe either this weekend, or next.

By the way, if the corals do not extend polyps, how can they feed, other than zooanth., of course? Is there a response to a food item in the water?

Thanks
Richard
