Where's the Par Meter Thread

The Par Meter Thread:

In an effort to help local reefers D.A.R.C. has purchased a Par Meter. The meter is for everyone, and we would like to share it starting today. Here's the requirements to make sure that people will have access to the meter for years to come.

1) You must be a member of D.A.R.C. Not a member yet. Just send all of your contact info (i.e. Name, address, email address, phone #) to D.A.R.C@comcast.net. That's it.

2) You must have at least 100 postings on ReefCentral.

3) We will require a deposit, i.e. leave a check for the amount of the Meter. The check will not be cashed unless the meter is not returned.

4) You must post your name and city in this thread if you currently have the meter. Please then contact Freddie40 to make arrangements.

5) Please keep the meter only as long as you need it. When you are finished please return it to Dave, Rob or the next person in line.

Sorry to be so strict, but Denver is a very big community and D.A.R.C would like to keep the meter for a long time.

Thanks,

Dave, Rob & Grim

So I did some testing with the par meter. Here's my results.

My tank 75 gallon
Lights: 6-48" T5 bulbs: From front to back Sfiligoi Super Actinic, ATI Blue+, KZ Fiji Purple, UVL 75/25, ATI Blue+, Sfiligoi Super Actinic. The 4 in the center are on a Icecap 660 and have Tek Reflectors.

1st test: The 2 Sfiligoi bulbs have Icecap reflectors. Par =265
2nd test: The 2 Sfiligoi bulbs are turned off. Par = 215
3rd test. The Sfiligoi bulb in front has no reflector. The Sfiligoi in the rear has a Tek reflector. Par = 242.

This has been helpful. I know that 265 is probably too much par. So I will run the front Sfiligoi without a reflector for a while to reduce par.
