upgrading to metal halides?

CarolD · 01/21/2006, 07:44 AM

I'm planning to upgrade my 55 gallon reef tank from a Coral Life fixture to the Aqualight Pro HQI which has metal halides. Do I need to make the change gradual? Just wondering if I can harm any of my corals. I'm doing this because I have several hard corals that need an upgrade in lighting.

Thanks in advance.

What were you using prior to the change? It can shock the corals for sure, Do a gradual change.

I was using a CoralLife fixture with fluorescents. I run everything on timers, and have many beautiful corals. Should I start with just a couple of hours and increase an hour per day? Just don't want to ruin my corals. Current fluorescents are 2 - 10,000 k sun and 2 - 65 k actinics along with a moonlight at night. I'm excited about the upgrade, just need consultation and want to be carerful.

Thanks much!
