Coraline Algea not growing.....

[RayAllen]

I have never had this much trouble growing coraline algae. My 39g just refuses. Ive recently started dosiing 2 part everyday 2 weeks ago. My display will not grow it, but my fuge under a low wattage florescent bulb is growing it now at a good rate of speed. What gives why will it grow in my fuge but not the display under the MH. Same water so the only thing that makes since is the lighting. Maybe the color spectrum differnce??

lower wattage and higher spectrum grow coraline faster. that what i remember reading from garf long ago.

Yep, coralline doesn't like high light.

I HAD BETTER LUCK WITH PCS OR T5. if u add some t5 actinic it might help

ditto...once I added t5 actinic my coralline took off

[RayAllen]

Thats what I was affraid of. I may sale the MH and go T5.

Also coraline will cover acrylic much quicker than glass if you have an acrylic sump and glass tank. I always noticed my overflows would be covered long before my tank, and the lighting like others have mentioned.

add something small like the one i traded coraline79 its dual t5no wont take up much room have it come on before or after mh. it will allow for night or early morning viewing. and it wont interfer with the mh bulb u got and like. also think the wave length from the actinic will help with anenome

I have the same problem, and I have been dosing for almost a month or more

I have a 14 gal biocube with this problem too. I turned the lights out for 72 hrs to help rid a diatom bloom. When the lights came on their was spots of coraline everywhere. I'm still waiting to see if it sticks around or grows (it's been a few days.)

Note: I seem to get better results on my 58 gal. when I rotate a 2part with my kalk drip.
