Thanks gps it makes sence.
led for me will cost around $100 delivered to the door from china @ 50w this is good as they offer 3 year warrenty and also can run for around 50,000hrs so a long time without changing the
bulbs. hoping to hyper drive the algea to grow faster if that can even happen the food source is inorganic compound eg the broken down food and fish poo etc I think.
If your interested in finding out some more here is a link, some guys posted on the forum what I think I am after. But if anyone else out there has some thoughts on the matter that would be great. it should take you to where I last posted.

another reason for led is I have them on my main tank (display)DT) and have had a great result they have been alot cheaper to buy than MH and cooler to run and cheaper to run and last 4-5 times longer than any bulb out there (apart from maybe plasma bulbs)
Thanks once agian
