New bulbs, now issues.

[bubbaque]

I have a ATI 6 bulb fixture on my 75 gallon. The bulbs are 8 months old so I wanted to change them. Last week I swapped out an old purple+ for a coral+, yesterday I swapped out an old coral+ for a new one and swapped a blue+ for a coral+. So overall I swapped one bulb last week and 2 yesterday morning. Today I look in the tank and notice my red planet doesn't have as much PE and possibly a little tissue recession at the base. I just noticed my spainbow's tips look kind of dry or maybe it's issue recession. It is not rtn. When I swapped the lights I raised the fixture 1" to try to help acclimate.

Could the new bulbs what is causing this? Did I not raise the fixture enough? What do I do now?

Try Cutting down the lighting period to assist in further acclimation. It's possible that The light intensity shocked your coral.

I agree, new T5 tubes are much more powerful than 8 month old tubes

If you haven't thrown out the old bulbs, plug them back in and use a par meter or so and check what the par is. Put in the new bulbs and test what they are currently running at. Compare the numbers and if it isn't much of a difference, you may want to check other things in the tank. If it is a major difference then just adjust your lighting to produce the correct par.

Turned out it wasn't the bulbs. I switched to rox 0.8 carbon instead of the old plain brs carbon and I put same amount as I was use too doing. Ended up being twice the recommended amount to use and it striped the water clean to fast and got stn. I did a couple large water changes and all is well now. Thanks for the help.

I always ran carbon so I initially didn't think I would have any issue but I guess the rox is more aggressive.

It is much more aggressive. BRS has a nice video showing how much more effective it is clearing color from the water than their other types of carbon.
