SPS and T5HO VS MH

[dreef]

I'm gung ho for quality T5's.as with individual reflectors,and quality tubes.Been using T5 for 3 years,very happy,never using anything else.

Thanks for all the comments! My tank is about 24"X 24" X 24" approx, and with my HOB fuge and skimmer, i don't have the room to set another duplicate fixture on top (although i have another 24" AL identical to the one i am running). The fixture has individual reflectors for each bulb and has 2X 420/460 actinics + 2 X 700+nm plus the LEDs and a built in digital timer, which is sweet. Based on what i have read, I should have decent PAR values from this set-up, but at what depth i don't know. I was considering getting the Odyssea fixture with the single 250w HQI MH + 2X65w actinic PC lights, then getting an ice cap ballast and different bulbs ($169US plus $181 Ice Cap ballast and $120 giesemann 250w HQi 14500k) for under $500. My rock is arranged like a wall with my softies on/near the bottom and my LPS near the top, but i am running out of room. Is there anyone in the Kelowna area that wants to sell some SPS frags so i can experiment?

What are 700+nm bulbs? Your actinics are really taking away from PAR. Actinics have lower PAR. I would suggest getting some AquaScience or UVL bulbs in there with at least one around 10-15K on your next change out. Instead of actinics use blue bulbs. If that was my fixture I would have 2 Fiji purple, 1 AquaScience 22000K and 1 AS 15000K. The AS bulbs have really high PAR even with the higher Kelvin. What brand are the bulbs you're currently using?

The 700+ NM are basically 10k bulbs, the others are a mix of actinic and blue and they are made by aquatic life as well, here's the linkhttp://aquaticlife.com/lamps/index.html

According to their literature, the set-up should be ideal for any type of coral, but i don't know enough to say whether or not that is correct. Their web site has some pretty detailed test results for all their bulbs, but again, i am not well versed to know what the results really indicate.

One potential issue with that fixture is the G12 base halide bulbs it uses. I'm not aware of any other manufacturer of G12 bulbs for reef use so you'd be stuck using only their selection of bulbs. There is much larger variety of DE MH bulbs and an even wider selection of mogul-based MH bulbs.

It says on their website that they use DE HQI bulbs, aren't those pretty standard? J&L sell quite a few different types of the 250 watt version.

This is a DE MH bulb:

Notice the difference with the g12-based bulb shown in the link you provided? The g12 plugs into one end, a DE bulb slots in on both ends, a mogul bulb screws in on one end.

May I know what bulbs you are using for the T5 ?

When I stopped using ZEO my ENTIRE system had a major brown out(almost all SPS and 1 large duncan colony), so I thought this would be a great time to re-do the whole setup. Out came the halides....in went the T5's, also removed 80 pounds of rock. built new rock towers put in brown frags from mother colonies, and 3 weeks later i'm starting to get color.
Weird thing is, corals that where once green are now starting to show signs of orange and yellow with green polyps....pretty cool actually.
So to make long story short, I like the T5's for SPS.

The link i provided was to the Aquatic life T5HO that i use now, the Odyssea link is here http://shop.aquatraders.com/ProductD...ductCode=54201 and if you mouse over the picture of the MH bulb it looks identical to the one in the link you sent me..no?
