Anyone else have the "problem" of not getting any coralline algae growth?

Be careful on what you wish for. I know on my 170 gal i had in the wall where the 150 is now. I had huge Coraline growing it was peeling off and I was going thur CAL and ALK like crazy...... SO theis time around im scraping it off because it will suck the life out of CAL and ALK..

Andrew what are you using for lights again and what colors, and how long are they on for?

I had a zero nurtrean tank in my 90, My Mg was the same as yours, I feel your Ca is way high. I found much over 400 and you actualy get a slow down in growth in SPS. I used to try maintain mine at 380 to 400. I also had my alk a little higher than yours, 12 if I recall right.

I had SPS growth and color that poped, with nice deep colors. I was running Pure actinic 12 hours a day and My 10K MH for 8 hours a day, and I had to clean coraline off the glass every other day and it would plug my tunze in about 2 weeks to the point if the power went off they wouldn't restart.

personaly I think it was the extended actinic period that did it, in combanation with a elevated alk and a natural level Ca.

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.

ya, give that a try Andrew, one other thing to note is that the different colors of coraline seam to coraspond with color of light and intensity of light. oh do all you bulbs turn on at the same time? is there a way you can do the old "pure actinic comes on for a couple hours then the rest, and opposit at night? that might encourage more purple growth.

Not much Coraline, BUT, alot of Cyano LOL
