ETRC Meeting - Dave & Nicki Stevens' house
Meeting sites- The future location site of meetings
was discussed. Club members felt that meetings at other members houses
would be best. The Dec. Mtg. site was discussed. The members decided that
it would be a good idea to have a social meeting in December, possibly
at the Italian Mkt and grill.
Officers- Chet Peterson asked to resign from the
position of Vice President via e-mail. Mike Teague asked for volunteers
to be V.P. Art Curl volunteered and was approved by the members present.
Future Topics- Suggestions were requested for presentations
at future meetings. The following topics were submitted (1) pH, (2) calcium
and alkalinity, (3) coral toxicity.
Lighting - Gould Smith gave a presentation about lighting the Reef
Aquarium. Reef lighting needs to take two different qualities into consideration
1) the strenght of the light; 2) the spectrum of the light. The human
eye sees green light the best. Violet light is very important for reef
photosynthesis. The amount of light reaching lower areas of the aquarium
is much less than apparent to the human eye. The strength of light is
decreased by a square of the distance from the light source. The next
discussion was related to the different Kelvin ratings of lighting. PAR
is a common strength rating of light bulbs (larger number is more powerful).
CRI is the color rendition of the light. It also appears to be important
to have a dusk and dawn period with decreased intensity of lighting.
