Overdriving lights.
Hi,
Depends how DIY you want to get...but $200 to $300 is the price range for a 250W Iwasaki single fixture. $100 for the lamp...so the fixture can range between $100 to $200. MV are $10 to $30...

Merchandise??
Hi,
I guess it is the "membership fee". (Just kidding).

Kalk reactor
Hi,
I believe a common method of reducing CO2 to kalk reaction in a large tube is to place a large piece of styrafoam on the surface. This reduces the surface area which the air (CO2) can react...

tank with no center brace
Hi,
I believe Hagen tanks don't have any bracing on their 4 foor tanks. A little bit more expensive than Seastar (maybe %15), but IMHO their tanks are better built. I can't remember if Perfecto...

What would the spectrum of the lighting system tell us ? I thought what matters most is the intensity that a coral receives or lux.

Hi,
In general, higher lumens (from a MH) usually allows one to light up a deeper tank. If you are supply 200W to a 400W blub...then you will produce approximately 50% less lumens. By using two...

Typically (not all lamps and ballasts are the same...but usually for 5500K),
175W MH draws 2 amps and produces 12000 lumens (8000 lumens over 1000 hours).
250W MH draws 3 amps and...

Hi,
Aluminum Flashing with white paint (or aluminum foil).
I don't think I can use Mylar...it would probably melt due to the heat.

Hi,
You mean 220V 3 phase ? I don't think they have 440V...they have 347V, 600V and 3KV...but I haven't heard of a 440V 3 phase. Must be a new electrical format on the island (just kidding !)
