Once again Len.. Thanks.... I ask because I'm making the Canopy and can still raise it if necessary... Just want them to be happy.... :wink:

I had a quick question.. How Hig above the water should I place my 10k 400W MH bulbs? I have a 75 AGA that's 18" deep. The Canopy I'm building is 12" above the water. I figure after mounting the spider and socket the bulb would be ~9" from the surface. Should I place them further away...

Thanks Leonard... I bought the 400Watt.. and the German bulbs.. Does that mean I'm not getting the most out of them? is this a European bulb(Since Germany is in Europe)? Or Does it only work with Ushio? Do I have to look spefically for Ushio bulbs? Thanks again you've been a real...

Then I have a question... when you buy a PFO-HQI ballast from MarineDepot. Does that mean you can use both double ended and Pusle start? What exactly are you getting? I ask because I bought one and am using a Mogul and all the "HQI" bulbs are double ended. I haven't found one that says...

Had one and it lasted almost a year but I had to feed it with a syringe.. It's not worth it. and you're right most die from starvation and then your left with two shells..

I've bought over a few and my favorite Aquatic Specialists. But I think the thing that I noticed is what type of rock you want and what kind of reef you want to replicate. If you like fiji then I agree with the above. But I prefer Indio pacific. It look more attractive IMO. It is a bit more...

Yup its a good thing. It means your on your way. I would use some kalk instead of the buffer. Just my opinion..

Hola Hector I'm also looking into geting some light. I'm doing the dual PFO-HQI 400w ballast. One thing I've incounterd is that they don't have them in stock. So before ordering make sure they have them in stock. Otherwise you could be waiting for a long time. I know that the Bluline...

Howdy.. New to the group here.. I was thinking about upgrading to MHs. I was looking at getting some 400w with either 10k or 12k bulbs. Correct me if I'm wrong. Are you saying I would need a chiller if I used these? What if I went with 175W instead? I couldn't afford the extra cost of a...
