kangym -
Thanks for posting your PAR readings. Being a former "T5 guy" I find it interesting that the shorter bulbs produce less PAR/watt than the longer bulbs. I almost went 10x39w T5 on my current tank... glad I didn't! Instead I switched to 175w halides and low light corals, life is so much easier when everything is brown and green By the way I posted some pictures of your tank here: http://reefcentral.com/forums/showth...readid=1647872

Thank you Jacob. Let me know anytime if you need the par meter. If possible, please chime in and share your par data here.

So a 24" T5 bulb will be weaker than a 48" T5 bulb. You would think as long as its directly under the bulb it would priduce the same PAR reading excet the longer bulb would have this readign over a longer area. Am I wrong to think that?

I would like to invite those "all T5 tank" owner to chime in if they have par meter at hand. Then we will be able to find out the secret of par production and the length of the lamp. |

Ok, it is about time for the par reading.
Everything is still the same, 10 x 54W ATI Powermodule 4 in. above water level Guess what? Yes, it drops. Par reading on May 2009 Par reading on June 2009 |

Thanks homeboyreefer and gem_nut85.
Find an interesting article referred by reefmaster3024 from CVR: http://reefkeeping.com/issues/2002-02/totm/index.php My new lamps have arrived. The par drops almost over 30% after 10 months. The growth rate slows down, and I start to have difficulty to keep the brilliant color. Is it about time to replace with new lamps? Or hanging there for another two months to find out exactly how much the par drops. |

Front ATI Blue Plus UVL 75/25 ATI Blue Plus GE 6500K Daylight ATI Blue Plus UVL Actinic White ATI Blue Plus ATI Blue Plus UVL 75/25 ATI Blue Plus I didn't cheat and look to see what you are currently running but you need some red in there. The 3 UVL lamps should be plenty and the GE should help bring out greens nicely. You could try swapping the position of the 2 and 3 lamps so the dusk/dawn is a 75/25 and blue plus. Kinda neat effect for a change from the normal blue. I would get an ATI Aquablue as a spare just in case the actinic white is a little too much with the 75/25 lamps. .

GE 6500K is very good for green and yellow. ATI aquablue spec. are no more included in my favorite list but as a spare bulb like your suggestion. The lamps combo in my mind was: Blue+ ATI aquablue spec. Blue+ GE6500K Blue+ ATI procolor Blue+ Blue+ UVL Aquasun Blue+ But now, I think I need to order some more new lamps. I will try your combo first. If possible, I will post the picture and the par reading. Thanks. |

One more question, does it help to use UVL lamp with internal reflector in ATI PM?

This is an interesting thread.
I am getting my 3ft DIY retroset with 6 x 39w t5ho soon. Gonna hold it over a 18" tank. Do you all think it will be able to hold the colours for SPS well? (: |

So what would we expect for the initial PAR difference when comparing the 2ft Ice Cap retrofit vs. the 2ft ATI PowerModule (under the same tank/height conditions)? The Ice Cap would be higher because they are the short bulbs, and they are over driven?
Also, would we expect the Ice Cap PAR longevity to be lower because the bulbs are being over driven, and therefore are wearing out more quickly? Finally, anyone want to wildly speculate on the initial PAR difference for a 2 ft ATI PM vs. a 150 watt HQI metal halide running a high quality bulb in the $80 price range? |

Replaced with new T5 lamps 2 weeks ago.
Lamps age: 2 weeks Light fixture 9 in. from water level The lamp combo from front to back Blue+ ATI aquablue spec. Blue+ GE6500K Blue+ ATI procolor ATI aquablue spec. Blue+ UVL Aquasun (Internal reflector) Blue+ The only difference is I took out one UVL aqusun, and replaced with ATI procolor. I will run this combo for a while to see if I like it? May try other combo later. |
