I'm testing and posting up the Par results over this weekend. I'll be dropping off the meter with Tex Gal.

Data collected. I'll drop every off Tuesday evening. I've added to the kit a pocket tape measure, small screwdriver and a 24" dip stick to hold the probe for measuring.

Results will be posted soon.

Robert, thanks again! Those are great additions to the kit.

As I understand, Tex Gal is next in line for the meter, then she will bring it to the holiday party on the 18th. Maybe Mike and Shane will let us dip the probe into their tanks, which are equiped with variety of lighting types.

I need to write up more of my own results, but I'm waiting for a new camera so that I can post photos of the set-ups. Soon, I promise.

As some may notice, we already changed our borrowing procedures a little. It was inconvenient for members in the far western parts of DFW to return the meter to me between each use, so it has been rotating among them since the last meeting.

Zapins, California might be a little far, but if you pay shipping. . . Seriously, I think the meter has been a great investment for our club, and has given some really surprising results.

Comments:
Are there other conditions affecting light levels? The water in my 10 gallon gets very yellow at times caused by Tanin. I’m trying to raise CRS and so it’s a delicate balance to keep enough acidic and soft yet clear enough for not to filter out the light.

What types of plants do you grow? I have plants in all my tanks including goldfish and marine tank. I grow whatever will grow in my tank.

Was the meter easy to use? The meter was very easy to use. I liked how it logged the samples for later to review.

Were you surprised by the results? Yes. I know the tannin in the water filter the light but I was shocked to see how much light I am really loosing .In my 35 gallon Hex tank, I was surprised how close of PAR value was to the 29 gallon tank. This makes me question the value of actinic in a marine tank.

Great post, Robert! It is really nice to see photos of the set-ups along with the information.

One question, are your spiral CFLs mounted horizontally or vertically? This apparently makes a big difference.

also on the antic's, note you are using power compacts, and not t5 h.o. from what I read t5 h.o. will give a lot more par, then power compacts.... I would also like to see what MH's will do.

I should of measured my saltwater tank too.

also robert, what zoas/poly's are by the blue green chromis is in the reef tank... if you ever frag some of those i would like to get a frag thanks...
