xenias only pulse at night (1 Viewer)

[yellowbelley]

for somereason i see my xenias pulse madly at night but while the lights are on it either will not pulse or pulse very little. everything in my tank seems to be fine. i have a 90gallon with MHs. only phosphates are out a bit but thats about it.
thanks

where in the tank are the xenia located? close to the top or near the bottom?

 

[yellowbelley]

it located like 1/3 from the top of my tank probably like 8" from the top

during the day does the xenia extend or does it shrivel up.. I think the intensity of the halides may be the problem. But I'm not 100% sure

Xenia are a living ph test.I would suspect that your xenia start to pulse at the peak of your ph which is right before the lights go out.Check your kh and if it is correct 10 to 12dkh then drip calcium hydroxide which will stimulate your potential of hydrogen. Xenia love light and will take as much as you can give.Good luck
