T5 lamp PAR readings

Thanks for the good work grim.

Can you recommend a 4- bulb (overdriven) combination to be used with 220 watts of VHO super actinic, resulting in a 14-20k look? I have a 20" deep tank mixed with sps and lps. I think I am going to ditch the 2 175 watt 20k halides, but want to keep color in the acros and not fry the acans on the bottom.

Thanks!
 
Hey Grim

I am a newbie and just joined reefcentral and I did some searching on lighting but would like to get a more precise answer from you. I have a 75g aga 48x18x20 tank, right now, im just cycling 45lbs of fiji rocks. In the future, I would like to have some softies along with sps/lps and clams. From my seach, I think I should go with the 48" tek hood from reefgeek. Should I go with 6 or 8 blubs? Will this be adequate for clams n hard corals? Also, I wanted a more blue look, like a 14k or 20k metal halide. Thanks in advance
 
Welcome to Reef Central!!! I have a 75 gallon tank and a TEK 6 bulb hood fits perfectly. You have an inch or 2 to get your hands into the tank.
 
thx my2girls, so what bulb configuration do you have? also, heres a very dump question i think..So do you guys also use timers to replicate 24hours, also how would you do that with a different variety of bulbs?
 
Do this

Front

UVL Super Actinic
ATI Blue Plus
UVL Aquasun
ATI Aquablue
UVL Super Actinic
Ati Blue Plus

The First and last lamp should be on one cord so you time those on first, say at 10AM, Add the next 4 lamps at say 11 or noon. Then reverse things at 8 or 9PM.

Which red bulb? The osram model 60?
 
i could surely use some advice. i am currently overdriving the following bulbs (39W) on 2 icecap 660's (3 bulbs on each ballast). i dont remember the order specifically, but the bulbs are;

UVL AquaSun (10K)
UVL Actinic White (12K) x2
Giessemann AquaBlue (11K)
Giessemann Blue Plus x2

Couple questions;
1) I feel its a little too yellow (i dont like the UVL AquaSun), so I would like to replace it with another AquaBlue. I think i want to have an overall 14K color appearance (when compared to MH), so is this the right direction to go to achieve this?

2) Do i get more usable light (PAR) due to overdriving the bulbs? I dont really understand how that works.

3) I am upgrading tanks, from a 58 (3ft) to a 150 (5ft). I intend to run the 54W 4ft bulbs over the tank (6 or 7 bulbs). I do keep SPS corals, and I feel this is plenty of light. Anyone else have opinions?

Thanks!
 
You have 4 whiteish bulbs and 2 actininc. Try adding another Blue Plus, they have almost as much par as the the white bulbs and will give you a bluer look.

You do get more PAR by overdriving. I think Grim found it was 30% more.

where else, besides reefgeek and premiumaquatics, carry ATI 39w bulbs?
Reef geek is out of the 39w ATI's and Premaqua is like $7 more than reefgeek.
