Watts on, Watts off

Wow that would be cool to see. Most 150 watt bulbs are very little more then 175 watts bulbs.

Thanks for your opinions guys, it's appreciated.

Some of you state that the WPG rule is sort of good because it is easy for the beginner to understand. That is of course true, but my point is that the rule itself is faulty no matter how easy it is, it is blatantly wrong and should not be propogated IMHO. I also read a lot quoting the word 'they' ( eg they say this, they say that ), well 3reef is one of the largest discussion boards around so how about 'we' come up with a rule? How about WPG/distance? Come on, you're all smart people, take up the challenge

Sorry about the misunderstanding, if you want to proceed in a different direction, start a new topic as I would be delighted to read your thoughts

Anything else would be stealing  I know several of these authors and edittors, I would never allow any borrowing of articles.

I agree Gresham. I didn't mean for us to take credit for their research. After all, we just wanna get to the truth no matter who gets the credit for it. Right?

 

I'm opening a new thread so we can dump research on zooxanthellae and pigments and how light affects them.

Its a general number guys, not a specific value like par.....I perfer to use par values if i have them...I dont right now. I gotta use something......now im shakin on it Gresh....im on the hunt for a par meterr. WHen i find one im going y par for my PCs until then, Depth, wattage for what type of bulb, and hands on experience will be my rating system. Gresh do you have acess to anymore of those meters?

It's the Quantum meter (with waterproof probe). Apogee has a hard time manufacturing these in the winter though, they calibrate them to sunlight (which may not be out in the winter).

 

[quote author=Gresham link=board=lighting;num=1107241757;start=15#15 date=02/01/05 at 17:08:45]I've measured 150w MH, 65w PC, 30w NO, 400w MH and 96w PC.  With out posting the data, what do you think the scale goes by?  Oh yah, discounting the bulb as well.

Most would say:
30w NO
65w PC
96w PC
150w MH
400w MH


My intank tests showed that a 400w with 6 months on it, at a depth of 12", put out far less usable light, then my 150 MH.  FAR MORE!

In fact, at the depth measured on the 400w tank, it compared to my friends tank with 2x 55w PC + 2x 30w NO.  


how much use did the 150w have on it?

 

Hmm, 4 or 5 months I think. I'm still not all here, so the data is still not available. I've been doing all night shifts the last few nights, I'm all screwed up.

 

I have seen the sun in winter...

 

Want a cookie? Any cloudiness at all, or hazeness, stops the calibration process
