Adding the GE in Place of the obviously bad 75/25 should take care of both your issues. You may end up wanting to swap the position of the GE and Aquasun

You probably want the cold spots on the opposite end from the vents. If you pull a lamp you will see a small hole between the reflector and endcap at one end. the air is pulled into the top of the fixture and blows out those holes, runs down the lamps and out the other end. You want the cooler air coming out of those holes hitting the cold spots.

Thanks for the clarification, Grim. Most appreciated...

Question: yesterday while running the lamps with the cold spots on the opposite end of the cooling holes in the Powermodule, the bulbs were brighter and the spectrum of many of the bulbs was differentâ€"overall they were whiter, particularly the Fijis and Blue+s. Do you think was because they were hotter and more "overdriven" with the cool spot not being cooled, and running hotter? What could account for this difference in the spectrum and intensity?

Will try that out. Thanks Grim. Since GE makes that bulb, can you find it at Home Depot, or is that still a special aquarium bulb.
I see Reef Geek sells them for $13.

I looked all over and was unable to find it at homedepot or any lighting store. I ended up just ordering on reefgeek and couldnt have been more satisifed with the service and shipping.. comes out to be a little under 20 bucks if I remember right
 
You should get paid by the post. I'm trying to set up 2 30g breeders. 1 for zoas and 1 for sps. I was thinking retrofit t5s from reef geek. how many and which bulbs for each? 30g being so shallow should i raise the bulbs up a little off the tank or go with 40g breeders? sorry if these have already been asked but there are soooo many post ?

Replace the Actinic Plus and Pure Actinic with a ATI Blue Plus

Replace the Aquablue with either a UVL Aquasun, Giesemann Midday or GE 6500K Daylight. Move that lamp up to position 4.

thank Grim. I'll try that.
 
Just a FYI for anyone out there looking to purchase RG reflectors....I called them today to find out where I could purchase them due to the fact they do not sell them, but to my suprise they are going to be listing them on their website starting in January. But if you are looking to get them now they are very helpful and will accomodate you by taking your order through them and shipping them out to you. Great place to work with and I would definately reccommed you give them a call if you are interested in not getting middled.

Does your fixture have controllable fan speed? If so try slowing the fans down and see what happens. Over cooling the lamps will definitely lower the output.

I should get paid period:lol:

You can raise the fixtures a bit if the corals appear to be getting too much

what do you think about # of bulbs for each tank and which bulbs? they're going to be frag tanks so I'm not worried about aesthetics but more about good growth. the reason I mentioned raising it up is because I didn't want stripes of light and no light. thank you

Hit them with full spectrum with lotsa blue

Id do 2 ATI Blue Plus 1 GE 6500K Daylight and 1 UVL Aquasun. The Sun has a little more red and the day more green, both a bit of yellow. Should give you tons of PAR and all the spectrums.
 
couple of questions i have a 50 gal breeder and i want to go get a new t5 fixture. im looking at either tek or ATI. where can i find the ATI sunpower fixtures and is ATI really worth the wait? my other question is would a 4x39w fixture be sufficient or would i be wise to get the 6x39 up front? does anyone have fixtures from either ATI or TEK ?
 
I am setting up a 90 gallon (24 tall x 18 deep x 48 long). I want to keep SPS, LPS, clam, zoas, and ricordia (where i can make them happy). Should I go with 8 bulbs in aquatinic reflectors or with 6 bulbs in slr reflectors? I will be using 2 icecap 660's regardless. Reason i dont just go with 6 aquatinics and expand to 8 later is i get a good deal on icecap, but i can alway consider 6 aquatinics.

will it be too much PAR for the 13" high zoa frag tank? what ballast/reflectors do you recomend if i piece this together?

I'd do the 6x39

Not sure when the Sunpower is available. Check with Reefgeek.

The ATI's are the best but a Tek or even Aquactinics Tx5 would work well too. The Tx5 is a 5 lamp unit that might be your best option.

Id probably do 4 lamps in Aquactinics reflectors on an Ice Cap 660 ballast and 2 lamps with Aquactinic reflectors on a standard T5 ballast at the front of the canopy. If you keep the Ricordas out front under the HO lamps they should be happy. Brain corals too.

Grab one of the old style Nova fixtures. Should be dirt cheap. Even a flat reflector will give you plenty of light for a 13" tall zoo tank.
 
Hey grim, what do you think about the sunlight supply tek 8x54 for a 90gal bb sps dominated with all zoas on the bottom of the tank? Would the lack of fans impact the output to much? What would you reccomend for the bulb combo?

Thanks, Brian
 
Hey guys some questions for you, im buying a new tank this weekend a 70 gal tank that is L-36.5xW-18.5xH-25, and i think im gonna run T5 on this tank. Im alittle confused ive been running MH on my 55 gal which is ok, but i really like the look of T5. This tank will be sps dominated, and looking for the best T5 combo for this. Right now the only lights im seeing for a 36" are 6x36watt, and im not sure thats enough or not. If its not can someone please recomend a light fixture that would be better, and one that i might not have to hang from the ceiling, but one that would go right on the tank since it will be in the living room not sure i want to hang it. Any help would be appreciated since i know nothing really about T5. Thanks everyone
