I still do not fully understand teh lighting requirements for my work-in-progress reef tank. I am not sure if the combination I am running appropriate. I have a 55g. I have arranged the rock to slope from the back left corner down to the front right to allow optimum exposure. Right now I am running:
130W which is a combo full spec\actinic. 10,000k, 440 nanometers. They run twice a day for 3 hrs.
I also have PC
110W Actinic. K
? nanos? They run for 12hrs a day.
Even with my full specs on for only 6 hrs, I still have a bad algae prob. (green film algae on the glass every day) I use RO
water, run 2 backfilters with carbon, 50lbs LR
, skimmer 24\7. Lots of water movement in the tank and across the surface.
My many questions are:
Is the nanometers the factor that effects algae growth?
If so, waht range should I be looking for?
Is the combination actinic\full spec. totally wrong?
If so, what should the blend be using this amount of wattage?
What about the length of time for each set of lights?
My tank has been up for 10 months now and at this stage I was hoping to be a little more self maintaining.
I love to work WITH my tank but find myself working more ON my tank.
Thanks for your help
