Thanks guys!
Did anyone ever get it to be red/pink? I see that all it needs is for that to happen would be more light... I just got two more of 6700 HO so with the two 10000 HO that I already have that would be (31+4)/30 = 4.1333333333333333333333333333333333333333~~~
Over kill?

are you doing the watt per gallon rule? that rule does not apply for HO. YOu will end up creating algae farm for a 30 gallon if that's what you meant by the math you just did. BTW it should have been 31*4/30.

viwwo said:

Wow you are right... it should have been 31*4 and not + :icon_redf
Yeah, I had a feeling that it was a bad idea with all the HO's. But so I do have:

2x 18w 6700
2x 18w 10000
2x 31w 6700
2x 31w 10000

And what I have running now is:

2x 18w 6700
2x 31w 10000

But I can play around with the light combination. I have two 30" coralife lamps. Both hold two lights... so do the math

(2*2)+8^24/6053=4

I can have up to 4 lights on my 30g. Should I keep it the way it is?

TO be honest, I think 1x18w 6700 along with 1x18w 10000 on top of tank, will give you enough light (low to medium at the substrate level). That was what I started out with. I do not have a par meter, but went by the data and chart Hoppy put together for the ppl here(sticky at the lighting section). Anyways, I am sure if you go by what you have now, you are putting too much light. but again, if you raise the light a significant distance above your tank you could be fine.


BTW, the number of combinations should be C(4,2)^2=36 possible combinations.

with viwwo's math and sutff, i personally look more at the Kelvins as opposed to the WPG, even though the WPG can tell you if your going to be having an algea tank or a planted tank.

Lol.. you know I was joking about the "(2*2)+8^24/6053=4"

The light I have now works well and the Rotala rotundifolia is pinkish. I was just wondering if more light will make it red. But I can live with it because pink is better then unwanted green (algae).

So I'll stick with 2x 18w 6700 & 2x 31w 10000.

lol... I have guessed so. You couldn't be off by that much(procedure wise).
