How many t5 bulbs to replace at one time?

[rwm555]

I have a Tec with 6 T5 bulbs. I just purchased 6 new bulbs and was looking for some guidance on how many and how frequent I can replace the bulbs.

My LFS said to do one bulb (back to front) per week. That seems to little and to long. I was thinking about 2 per week.

Thoughts?

your LFS was pretty correct on this issue. only thing i see different and have heard different is only replace 1 bulb at a time and i do believe you should wait longer then a week to change the bulbs after the first bulb. i cant remember were i read that at but i think it was on the T5 thread here on the lighting forum.

the whole point is not to shock your corals and such from what i remember. its been awhile since i have read the thread.
