90 gallon lighting question

[falcon41176]

i have a 90 gallon with 2- 250 watt mh one 20k and the other 14k and 2- 65 watt pc 10000k. do you think it would hurt to add 2- t5 110 watts total one 10000k and the other a actinic.

Just your electric bill. I think it would be fine, but I would switch your 20k bulb to a 14k and run the t5's either actinic or blue. That should give you better balance across the tank.
