The t5s are 54w.
mh 150w
led using only 4w each- like I said, I don't have them running very bright. there is a peak of 5 watts each, just as the first two t5s come on and when they run for about an hour in the evening.
So, a total of 800 ish watts.
mh are on from 11 am to 8pm with a half hour off period around 3
m.
4 t5 (2b+ and 2cp) from 10:30 am to 9 pm
2 t5 (b+) 11 am to 10:30 pm
led start to ramp up at 8 am and finish ramp down at 11 pm
190 gallon display is 722 litres with 800 watts.. that's closer to 1.1 watts per litre.
i believe that i don't have quite enough light for some of my light lovers but on the other hand, I see light stress in some of the other not so light loving corals, like my jaw dropper that is up high.. The lower one has better, richer colours.
I also have two pink lemonades. one is up high and is in the photos next to my OP- it keeps decent yellow but I have another piece that is a bit lower and off centre and it is more green..
I really need to borrow a par meter.... I have to get on that.
My tank is also 26 inches deep and the central corals are not that high up in the tank..
I should probably have 250w mh for the light lovers.. But I don't have the room on my breaker.
I used to run the leds much higher and use the whites, but I turned them down to try to help with the light stress.. It has helped a bit, I think..
