Will actinics promote algea growth? Or just the "white" ones?:arg:
Go to forums, general reef discussion and there will be a "New thread" button.i do not now how to make a new thread i see nothing to click. i have a remora aqua c skimmer and it was tested at the store and worked great. i have a brand new saltwater tank with no life in it yet i hooked the skimmer up and it seemed to produce way to many bubbles and the collection cupped filled with water rapidly. is this just because the tank has nothing for the skimmer to collect yet?
+1CRVZ gave you the correct information... Light is light. Some is more useful at various spectrums than others and intensity plays a large role. Promoting algae growth is an outdated term IMO since it takes light, plus nutrients to grow algae. Removing or limiting nutrients is the key to keeping a tank with a minimal level of algae In otherwords if you have an abundance of nutrients than it doesn't matter what light you use, you will grow algae. And there is a direct correlation between light intensity, nutrient levels and algae growth.
Likely because you removed the light intensity in correlation to the nutrient level. Since corals are higher up in the food chain they have a bit more of a reserve for inadequate lighting that algae doesn't have.I had hair algae in a tank pretty bad kept fighting it and fighting it and final I took everything out(fish and corals) and just ran actinics because I had a little GSP and few other small things in there and the hair algae started to die and now its gone completely
I have also noticed a higher color temp on my bulbs greatly reduces the amount of algae that growsLikely because you removed the light intensity in correlation to the nutrient level.

Yup, as Hop points out, this is because you were limiting your light. Depending on the type of bulb, actinics will often have less than half the PAR output of similar wattage bulbs in the ~10kK range. So it wasnt the color of light that was limiting the algae, it was the lack of available light.I have also noticed a higher color temp on my bulbs greatly reduces the amount of algae that grows
