    Question on Kevin's ozone reactor

    Hi Kevin, I was looking back at previous threads and came across one on 6/11/07 called "ozone use..." I have toyed with ozone for a couple years but never really settled in on the whole thing. In the past I have used one of my skimmers as a "sacrificial skimmer" as it wasn't rated for ozone...

    SE lamps on HQI ballasts

    Kevin- I have experienced new bulbs not fireing on old ballasts. If I take an older bulb I can then get it to fire but not a new bulb. It's like the starter on the starter gets weaker as it gets older and dosen;t have enough power to ignite a new bulb. Guys- You have been very helpful and I...

    SE lamps on HQI ballasts

    I have a plasic shield on my fixture. I think it cuts PAR by 20% but I didn't like the idea of lamp stuff falling into my tank. Ed- It's interesting to hear yout experience with lamps breaking. I have a Blond Naso that lately really seems to splash on ocasion. I think I should keep my shield...

    SE lamps on HQI ballasts

    Very cool Kevin. I would love to hear your results as they come in. Hamilton told me that the SE bulbs have a starter built inside them but the HQI ballast comes with two of there own. The starter in the bulb is not designed to operate with the two other starters of the HQI ballast and...

    SE lamps on HQI ballasts

    Thanks Ed. It's cool to talk with someone who has run this combo. It's equally as cool to see some pictures under that lighting. Greg

    SE lamps on HQI ballasts

    Interesting. Your pictures look real nice and focused. The color looks great. Did you grow any sps under the lights? So what type of bulb life span did you get with that combo? I heard 6 months is pretty typical. Thanks, Greg

    SE lamps on HQI ballasts

    Ed, So you have used the Hamilton14k SE 250W on a 250w HQI ballast (just want to be sure I follow ya)? What type of life span did you get? How was the color? I heard it was whiter then the Radiums, more of an ice blue. Thanks, Greg

    SE lamps on HQI ballasts

    Hi guys (Kevin), I'm still struggling on my lighting decision. I want a bluish light with high PAR and came to the conclusion that the only way to do this without adding more actinics or jumping up to 400w would be to overdrive a bluer lamp with a 250w HQI ballast. Based on Sanjays work it...

    Are all M-80 ballasts the same?

    Thanks Kevin :)

    Are all M-80 ballasts the same?

    So wether I have a Sylvania M-80, an advance M-80, or a Magnetic M-80, the characteristics of a specific lamp (cct, ppfd, etc) should be about the same. Any differences are minor and are not caused by the ballasts being different brands but the fact that they are different ballasts (and lamps...

    Are all M-80 ballasts the same?

    I can buy an M-80 (hqi) 250w ballast at the local electrical distributor for about $80. It will not have PFO stamped on it. Any idea if the brand matters an these ballasts as far as how the cct and ppfd are affected according to Sanjays charts? Thanks, Greg

    where can you purchase krystal star lamps?

    I have googled myself silly and still can't find an online store that has them. Specifically I'm looking for the 250w 11,000k SE version that Kevin recomended to me. Anyone know where to get them? Thanks, Greg
