Reefnut · 04-12-2002, 08:36 PM

Hi I just wanted to get some opinions on my upgrading. I plan to upgrade my 135 reef from 3x 175MH and 2 140 VHO to 3x400MH and 4 110 VHO. The tank currently has all types of corals= lps,sps, acro, and soft. what lighting schedule should I start with, I don't want to cook my corals. Lets hear some replies. Thanks in advance for the advice.

I would cut it back to 3 hours a day to start and increase like 15 minutes a day till light regiment is reached.
I did this when upgradeing from PC to Halike and everything acllimated well over a few week period.
Upgrading to 400's will have effects on some of the corals though that all the aclimation in thw world wont help. Some corals just wont like that much light and will have to be moved lower or to shaded spots. Ecpecially mushrooms and some others. Will have to see how some react when new lights are added.
