ACTINICS??

[hobogato]

i just switched from uri super actinic (mainly 420 nm) to ati blue plus (mix of 420 nm and 460 nm), which is the same spectrum as geissman aquablue, and everything has more color in my tank now. the par is also much higher with tthe blue plus bulbs. the overall appearance of the tank is more blue than it was before, but it balances perfectly with the sunlight i have coming into my tank. i posted some pics last night and today in my thread.

Ace, gotta link to those bulbs and where you got them? What ballast are you using?

[hobogato]

i bought them at B&B here is SA. i am running two 39 watters and two 54 watters on a workhorse 7 ballast

Thanks, what would you suggest for a three, possibly four bulb settup as far as bulbs, endcaps and reflectors go, Im hoping these will work on an Icecap 430 ballast?

[hobogato]

not sure jim, since i am dealing with sunlight, i needed these really blue bulbs. more than one would overpower just about any other bulb.

Thats right,,,... Im using 10k, sunlights 5.5k so Id imagine half of what youre using maybe.

Jim, an icecap 430 will only power two bulbs. For a three or a four bulb setup you need a 660. WIth my t5 setup, I went all icecap for reflectors, endcaps and standoffs. Couldnt be happier. Also, icecap ballasts overdrive t5 bulbs so you might be able to get away with two bulbs. I also got all my stuff from reefgeek

I just ordered a Workhorse 7 from Frederick at Coralreefbazaar, should be here tomorrow. Already have the encaps, standoffs and reflectors. I will have enough gear to run up to four bulbs if needed. Now I just need to decide on which bulbs I need to balance out the Reeflux 10k. Thanks for the feedback! Anyone switch from VHO's to T5 actinics care to offer a review?

I switched from VHO Actinics and MH bulbs to an all T5 fixture and love it. Absolutely no heat and as far as the actinics go they were both made by the same company so I really can't tell a difference. I'm running the UV actinics which are made by same company that made the URI VHO's I was currently using.

If you were still using halides, which would you choose, VHO or T5's for actinics and why besides heat?
