Spiff,
I think 250W HQI is definitely the way to go. They are brighter and supposebly bluer than magnetic ballasts. Just a side note, the HQI tested by Sanjay was done without UV shields, whereas all other bulbs had shielding. I don't know why the discrepency.
I considered 250w HQI but after reading some discussions on the impossibility of a 250w bulb exceeding that of a 400w bulb plus HQI produces UV radiation, I decided to go large![] Also, my ceiling is not strong enough to hang a lighting unit with built-in ballast. Anyway, Rich Durso at http://www.rl180reef.com/ switched from 400w Ushio(running normal ballast) to Aqualine Buschke 250w HQI and is reporting good colour in corals(maybe its the UV). I think you can't go wrong with HQI. Wise choice.
I forgot to mention that in http://www.personal.psu.edu/faculty/...omparison.html Sanjays ballast test,
The 400w Blueline E-ballast beats the 400w HQI ballast in PPFD on Ushio bulbs. So forget about conventional magnetic ballasts, but E-ballast may or may not be less bright than HQI. You decide.

The T-5 tubes sounds hopeful. I've yet to see one in action. I could use some low heat actinics right now.
Agreed! The VHOs are trash. They are hot, expensive and short-lived. Only if you are desperate for light or using them for actinic supplementation then will they come into their own. On the positive side, they give a nice diffuse crisp white not available on MH and the colour is beautiful!
zhen,

Spiff,
No![:0] Thank you, but really not yet. [
When my tank looks better than Steve Tyree's then I'll consider.
I'll be really glad to frag them later this year if all things turn out well.
I bought 4 acros and a crocea from Reefworld. Maybe I'll be going coral hunting tomorrow.
The acros from Fiji are slowly turning blue. Which is a bummer cause I wanted pink and light purple.
BTW, how do you include html in the posts? They seem to work when I preview my post but when I submit, it doesn't work.
wah kao....blue is good!!
wa........i think i went earlier then u. i picked up a pink table acro!!!
