Nitrates at ZERO. From 20 - Here is what I did.

Probably, but that is a killer deal. Good Luck with it. You can use your 60 as the refugium. ;D

 

Hi ALW - I am a unsucessful calupra grower in my refugium. After reading your post I went to the hardware store (OSH) and to my suprise/consternation could not find a single low watts bulb in their entire stock that listed a kelvin rating on the package or bulb. I did find a durabright 90w 1380 lumen Sunlight. QUESTION IS, is kelvin rating only found on specialty/hobby lighting applications?. Thankx - wilrod99

 

Find a store that sells GE Daylight Bulbs. Here is a web page from GE that tells the specs. These are all 6500k

I saw this package at Publix Supermarket in South Florida. It had all the particulars except the Kelvin amount.:-/ Just a point of info..

 

Look for the package that says "Daylight" on it. Then double check the model #. On the GE you will be o.k.k if the model # is right.

The last bulb I got was from Walgreens. I will look the next time I am in there.

The Temperature rating was NOT in the same place as all the other info. Look at the whole package carefully. Line by line, even the itsy bitysy words.

 

Thanks to Phoenix Heights, I just found the light fixture on Amazon for $7.95.

Ahoy ALW: I wen't ahead and got a 90w Sunlight with a K rating of 5700 in itsy bitsy writing only visible when I took it out of it's pkg. Needless/obviously to say, I came home with it, installed it and i am getting some calupra growth but nothing to write home about. It seems that i remember reading in a past post about lights that give off a yellow light are not as efficient as daylight bulbs, 100w 6500k that i should have gotten to beguin with, I'll try that next. Thankx ALW - wilrod99

 

so have had lights going for a week or so and now noticing large growth in cyano, but there is non in DT. This is only happening on the glass and not on the sandbed. Just thought I would post.

 

Guys I found the exact GE daylight bulbs at WALMART--That same 2 pack was 5.75

 

Here is a 6-pack of them for under 20.00
