I've read of many people using the Galactica Luxmeter for iPhone, so I downloaded it and tried it out. At a time when my light was supposed to be at it's peak the best I could muster was 5-5.5k for a reading. I've read that 10k is kind of bare minimum as far as lux at the water surface goes.
This is a Kessil 160 on a Biocube 29. I guess I would have thought the number would be higher than that. I believe the Kessil peaks at 65 or 70% intensity, which I thought would be enough for a tank this size. I have had decline in zoa health and am looking at all possibilities for cause. I also have some zoa/palys that seem to stretch more than they should, which led me to check a little bit into the light levels.
Anyone have any frame of reference or experience with this app? I do realize a dedicated, handheld meter would be more accurate but I was just interested in ballpark.
