MH Question?

[jpeggerling]

I have a 20 gal AGA. Just got a MH pendant, 175 watts , with a 13k bulb. I have had a PC 65 watt 50/50 light on the tank for the last 6 months. I had the PC running 10 hrs a day. Should I not run the the MH that long? Everything seems to be doing ok so far.

I wouldnt,acclimate your corals. try 7 hours,then 1/2 hour every 2 days.

best way to do it would be to hang the pendant way high off the water and slowly lower it every day or two. light exposure time isnt everything, u have to take into account the difference in intensity.

Another good way for MH acclimation is simple window bug screen. Add a couple layers over the tank to diminish the intensity. You can keep the same lighting period. Just take a layer off every couple days and no problems. If you give them the full blast of MH without acclimation, you may kill off the corals.
