Lighting Question - Replacing Bulbs

[samt1]

Hi guys, I have had my tank going for just over a year now and re planted a few weeks ago and they don't seem to be doing to well so far, I have added a CO2 kit and also add liquid plant food. I have read that th lights need to be changed yearly?
I have a Fluval Roma 90 tank and the lights I have in it are:

One Power-Glo Fluorescent Aquarium Tube 15W 45.72cm (18in) T8
One Aqua-Glo Fluorescent Aquarium Tube 15w 45.72cm (18in) T8

Anyone have any suggestions for bulbs that might be better suited for the plants or would just replacing what I have do the trick? Or are they fine as they are.

Thanks i advance for your help
Regards
Sam.

Hey Sam.

Bulbs will start going bad around a year typically. Replacing them every year is recommended. Regardless of the brand of bulb, you will want something in the 6500K range for a planted tank.

Thanks mate, I'll start looking into replacing them.
