AB special Blue+ Pro Color Blue+ AB special Blue+ All tubes run on Vossoloh eballast. There's no need for cooling of the tubes or ballasts because usually when the lights are on, I am in office with my air con on directly above the retrofit (: HMM. I am not so sure either. The readings were given to me as such. I am equally annoyed that my readings are that small. But right now, all my zoas are bleaching under the lights, even the healthy ones are flattened out under the lights. So I wonder if it's really the lights or just my water parameters :X Nonetheless, I will try with a monti and see if it can hold its redness to see where I am for my T5s (: anyway bro, what fixture are you using? and what tubes? (: Happy Reefing, Marc J. |

A sfiligoi with retrofitted cooling, and aquascience tubes. I would be very surprised if you didn't benefit from active cooling as even a 'bare' tube (tube + endcaps) runs too hot. You should be able to hold your tubes comfortably as you want them to be running as close to 35C as possible. All the same, those numbers look duff to me.

Generally, the par drops around 5 - 7% in one month. Overall, the par number still looks good for sps. Growth and color are nice. No plan to lower the light fixture at this time.

I am not using a sfiligoi set. Mine's a self-made retrofit with active cooling fans, so yeah. Somehow I still don't find 6 tubes are sufficient to me. IT'S WAY TOO CALM for my eyes unless I look into the tubes directly. If not, through the glass, the effect is mild. Could it be something to do with my eyes or my 12mm thick glass? Anyway wayne, the readings are inaccurate. I remeasured the LUX directly from the tubes last night. They were at 47000 LUX, 3 inches from the tubes (or on the water surface). Is that a crazy reading? LUX to PAR is a divsion of 51 from the LUX readings. So I am getting like 921 for PAR?! Happy Reefing, Marc J. |

Kangym:
Those readings look great for the 54watts (: Anyone mind chiming in the readings for a 39w? I kind of regretted going for 39w when 54w seems to be the way to go hah :X Happy Reefing, Marc J. |

I am thinking of replacing the 3ft ATI PMs in my 265G with either 10x80W ATI PM or Sfiligoi 12 x 80W. I wish someone has par reading of 8, 10 or 12 x 80W T5 could share the data with us.

Kangym: why do you want to change? Any reason?

I would worry about the coverage of a 5ft fixture over a 7ft tank.

Compare to 4 ft T5, the par reading at 5 to 15 in. of the 200G tank is around 400 and more. So I am surprised to find that 4 ft T5 produce more par than 3 ft T5. If you check rhoptowit's previous par reading on ATI 2 ft PM, it seems even 2 ft PM produces a little more more par than 3 ft PM! It is just my observation.

Again, I will prefer to know the par reading of 80W T5 before I jump in. Anyone would like to chime in? |

Coral growth in less than 3 months under T5 is just amazing:

Im wondering how a 8 bulb 2ft ATI PM will do on a 24" deep tank. Wonder if it matters if I go 10 bulb unit, or 8 bulb.
I am jst now setting up a 60 gal cube, and havent decided on lighting yet. |

I do not know the answer because I never have a chance to test the par on 2 ft ATI PM. Here is the par reading from previous posting by rhoptowit. His tank is 12 in. high and he is running 4 bulbs 2 ft ATI PM. At the sand bed level, the par is 328. You will get more par with more bulbs for sure. IMO, 8 bulbs will be enough with all high light animal placed at upper half of the tank.
You should try T5 Q&A thread, I always get very helpful information there. Quote:

Yes, we need par reading for 5 ft 80w T5 and 2 ft 24w T5. Anyone?

I was considering the 5 foot 80w bulbs. These PAR numbers would be interesting to have!

I pass the par meter to local reef club members to test their lighting. It won't be back for another two weeks. Will post the new reading as soon as I get the meter back.
Still looking for par reading under 80W T5 lighting. eros just got a new 24in T5 lighting. It will be interesting to see another 24w T5 tank par reading soon. |
