Hi Steve,
Right now I'm running 4 x 24W Tek light while I wait for my ATI 6 x 24W Sunpower to come in. Today I actually swapped one of my AquaScience Duo lamps for a UVL Actinic (420nm) just to see if bluer coloration makes a difference. Prior to swapping lamps today I was running 2 X Giesemann Actinic+ (mostly 450nm - a "blue" lamp) and 2 x AquaScience Duo (around 15,000K - a "daylight" and "actinic" combination). This combination was fairly white with a hint of blue and now with the swapped out AquaScience Duo for a UVL Actinic it's much closer to 20,000K looking.
As far as calcium goes I struggle with keeping it down while maintaining my Alk higher despite using Reef Crystals salt which I bought because I heard it had high Alk and and low Ca - but so far it's tested quite high in Ca. I think I will shut my doser down over the next 24 hours to see how much my Ca drops and then re-adjust my Ca dosing to keep my Ca around 425 and Alk around 10dKh. Then I'll just dose to keep Ca around 425 and Alk around 10dKH without worrying about equally dosing the 2-part.
