how much light is enough

[fish-unit]

im setting up a tank now 1100l by 650 h by 500 w

would 2 150w metal halides be enough to keep hard corals?

[reef]

would not be a problem at that height.

agree with reef.

I would watch the height of placment and lower them accordingly, rather than have them too low to start with.

would i need to upgrade later or would that be enough for that tank,i dont want to have to upgrade wanna get the lights done properly first time,also i hear you sell 150w metal halide bulbs for 35 bucks is that true reef

Hard question to answer. That amount of light will grow acros. In some cases 250 watt halides would get better results but there would be debate over that. The best way to REALLY know might be to look at a few peoples tanks & their lighting & the results, so you can get an idea what you want to do.

As for the second part of your question there was somebody selling bulbs for 35 bucks but I don't think it was Reef. Also I doubt you would get quality for that price although I'm always happy to be surprised! :lol:

There are medium quality type bulbs for $65.00, but for high end ones you are looking at at least $120.00 plus.
