Whats gonna happen when iI increase light conditions? I have ran low tech tank with 40 watts of light on this same 55 gal. I fertalized about twice a week.I'm planning to utilize a D.Y.I. C.O.2 system and i"m looking to utilize a 500watt metal halide fixture. So my question is this too much light? I want to be able to support baby tears in the forground and a few other high light plants.And if it's too much light then how much do I need? Is it possible to have too much light?

I would definitely reduce lighting. You would need a pressurized CO2 system with those and even then, you'll be fighting algae constantly in my opinion. Thats about 9 watts of MH lighting per gallon. That is very very high. I would look into two T5HO lights over the tank for some nice high light that will support baby tears. But even then, you should really use some pressurized co2

You would need pressurized Co2 and you would need to have the light a good few feet above the tank or else it wont cover the edges to well, It depends on the reflector and the bulb etc but without co2 I wouldnt consider it. I have two 175 mh's over a 50 b and that is more then I need but no algae problem but some plants really do not appreciate that much light and the level of growth I am getting could easily be achieved with many fewer watts of more efficient bulbs ie t5s or even overdriven t-8s. But I had the lights and I dont pay extra for electric. why dont you put your light over a 5 foot diameter baby pool and grow in that it would make more sense.

500 watts is definitely way too much light, unless you want to be adventurous with algae invasions, lol.

Reduce to the 2 - 3 watt per gallon range, imo.
