I will be coming up on the time to change out my bulbs in another month or so and I am considering changing to 250W ballasts and bulbs. Hoping some people will either talk me in or out of it. My tank is roughly about 28" deep. Here are my thoughts: Am I getting too much usable light? Am I getting any decent actinic dupplementation? Holy crap my power bill is high? Wow my fish room gets really hot even during the winter I know some of my growth and color has been fantastic but will it change that drastically? Very torn.
