actinic, will the plants be all jacked up? and how bright will 130 watts be?
1 65 watt actinic and 1 65 watt 10000k bulb
1 65 watt actinic and 1 65 watt 10000k bulb
I feel very strongly that actinic lighting does not contribute to algal growth in freshwater tanks. Its only effects are cosmetic
hashbaz said:Perhaps this is yet another very common misconception.
All plants and true algae have Chl a and have chloroplast.
These are what capture sunlight and use it to produce NADPH and ATP.
There is no light that selects for plants but not algae. There are very subtle differences in deep clear waters in marine systems that let one alga get a jump on perhaps a another species allowing it to dominate for a time.
Not exactly a valid comparision.
Atinics will not help nor harm a tank, wasted light in some respects.
Some claim blue produces compact growth, I've never seen any difference over some 2 years of growing plants with many bulbs. Cool whites do just as well as pricey "fish plant" bulbs. This was shown in green house studies and was a well done study.
It really gets down to aesthetics, do you personally like the color or not?
I like Triton bulbs the most, i have had ther 8800K and 5000K mix, I like that mix a lot but the Triton still is my winner. It's 7200K, not that it(K ratings) means much.
6700K was fairly blueish when they came but now people are saying it's yellow
If you like then atinic for the color, use it.
It's not going to make your plants grow better/more compact though.
