Duncan question
 

So I got a frag about 2 weeks ago.when I put it in the take about a hr later it was slightly open.I gave it a few days and it still never fully opened.I looked one night after the lights where off and all 5 heads where fully open so I figured my lights were to bright.I moved them lower and of to the side and they r still doing the same thing and I can't really give them less light.I have the aI prime hd and the duncan is off the the side in my 20 gallon long. Thanks everyone

Place it where you want and stop moving it around. Mine is under 4 T5s and 2 kessils on a 40 breeder. Probably 20 inches or so under the light. One AI prime over a 20 long is not anywhere near the amount of light mine is receiving
