lighting advice for a 125

i currently have a 175w metal halide on each outer third of the tank and have plans to put a 250w in the center which currently just a has a 55w pc. do you think that will be enough or should i upgrade to 250's on all three sections

 

How long is the tank? Do you have a more yellow temp bulb on the right side?

 

Good question. If so, it is a good example of how different lights impact differnt types of algae growth. Very cool!

 

there is a 6500k on the right and a 10000k on the left. thats something i have been debating is 10,000k or 6,500k

 

Sorry to be redundant, but how long is the tank? I would definitely upgrade all 3 (or 2 depending on the length of the tank)

Additionally, for the color, you could supplement with VHO or T-5's in the blue range.

6500 K gives growth, while the 20K end gives color. Look into the Radiums...they supposedly meet both needs somehow...don't know the details...

 

i have dual 250's hamilton retro kit for sale, with 12k bulbs all 5 months old, i agree tho upgrade the lights, i have the 250's over my 75
