I tested the par yesterday for my 265G tank, lighted by two ATI powdermodule 8 x 39W (3 feet fixture). ....... Disappointed.
Tank size: 84x24x30(H), 265G Lighting: two ATI powdermodule 8 x 39W (3 feet fixture) Light bulbs combination: from front to back Blue+ Aquablue spec. Blue+ Aqusun Aqublue spec. Blue+ GE 6500K Blue+ Hanging height: 8 inches from water level Age of lamps: 5 months Lighting period: 2 blue+ for 10 hrs, and 8 hrs for the rest. My apology, I forget to take the picture before I lowered down the left side light fixture. Both of them were 8 inches above the water level originally. |

Here is the par reading with fixture at 8 inches above the water level. Again, both fixtures were at 8 in. above when par was measured.

I checked the par in the beginning at water level, the highest reading is 850. Five months later, it drops more than 20% to 680 again just like 10 x 54W powermodule. I think the par are way too low to keep the sps. The growth is slow, color is dark.
I use almost the same light lamp combination. I though there is no difference between 3 or 4 feet light lamp. but the par reading on 3 feet lamp can not catch up with 4 feet lamp. Not even close. Here are the differences between two tank systems: 4 ft vs 3 ft 10 x 54W vs 8 x 39W Tank depth: 24 in. vs 30 in. Euro-bracing vs two trims Lamp combination? |

I decided to lower both fixtures to 4 in. above the water level. Check the par again.

The par reading still looks low to me to keep sps. Anyone has the same experience with 3 feet T5 fixture on 30 in. (H) tank?

I get better numbers than that with my standard output DIY retro. I was looking at getting a PM to increase PAR but maybe its a waste of money

I would like to see someone else compare 4ft. bulb against a 3 ft. bulb. Is the saying that 1 inch of t5 the same on all bulbs despite the length. I think maybe i should of went with 5 ft. bulb now!

Also, the 265G looks darker partly because of the tank composition. The 200G is filled with colorful corals almost to the top whereas the 265G rocks and frags only goes up halfway of a 30" tall tank, leaving a lot of background. I think the lighting is sufficient for a mixed reef and it will turn this frag tank into a full blown reef in no time. |

wow i was just talking to my lfs about this, as i was about to buy a 36" all t5 fixture and they told me that i would be dissapointed with the par on a 3ft fixture as opposed to the 4ft fixtures (both ati powermodules) as they said the 4ft in their opinion put out much better par, i didn't really take it seriously as i thought the intensity would be the same but just in a shorter area of 3ft vs 4ft, i would love to see if we can do a proper comparison as i might just stick with halides mixed with t5 supplementation.

SWEET TANK.
Imitation is the best form of flattery. So,,, with that said,,,, What is some of the other equipment you're using in your display tank? (IE: skimmer, pumps, chemicals, food, feeding schedule, etc) I bookmark a few of the truly inspirational tank threads I come across, and yours is now one of those few. Thanks! |

Why did you switch from 400w MH to T5's?

lights are 4ft and about 4inch from the water. I get about 600Par just under water level About 400 at 12 inch about 250 on the sandbed. I wanted to get a 10 bulb PM for my next tank as i assumed the par would be much more. |

Water current effect PAR reading? If so, your PAR reading is with water current? Or shut off PH when you measure PAR?

Sorry. Dont have any exact pics. I'll have to borrow the par meter again soon and do some better testing.
