Question Blue ochtodes not blue in my 20 g fuge!

I have 2 frags of blue ochtodes the size of 2x3".

They aren't blue, just grey and light blue on some areas....

I have 2x24w white and purple t5s.

Does it need actinic lighting to show some good blue?
Thx

Blue ochtodes is not a blue macro. They really need to change the name to purple ochtodes because that is the color. I'm thinking a gray color means a lack of light.

Does actinic or purple t5 bulbs do *anything* to caulerpa and other red macros?

Or is it a waste running them along with a day light (white t5s)?
Pls advice, thx

460nm is typically what you are looking for from a t5 for photosynthesis, which would be a blue colored bulb. Purple is typically used for the colors it produces. Daylight bulbs can be good with macros also.

I just got some ochtodes from the recent frag swap in the area and just posted some "update" photos in the local forum here for the club. This might help reassure you somewhat. When I first got the algae, it was not very colorful, more a rusty red/brown. I am running straight power compact lights (96 or 98w, 10k/actin) in a Coralife 36" hood. Less than a month later, the octodes has colored out (and I think grown a bit), showing a nice deep purple color under 'daylight'.

Hope this helps somewhat in what to expect!

Thx for the info....

Will it look blue only under some combination that involves an actinic or will it eventually turn blue even under daylight alone ?

Reason is I right now have it and other macro under 2x24w t5 10k/purple. Wonder if I should replace purple with actinic?

Thanks!

Macro algae responds to light similar to other plants. White light only is good for seeing the tank, blues and reds are what gets then to grow. If you want a super healthy fast growing refugium that really brings out the colors of the macros, then you could do something like what I have. I use a 240w red blue and orange led fixture above my refugium, and I have to pull out the overgrowth every week. I have about 7 kinds if macros in there, and they are all going crazy. Of course having the right nutrients present in your water is a big part of their growth and color.
If you aren't getting te color you want in your macros, then you should make sure you have enough fish waste to supply their nutrients, and add red and blue colors to your lighting spectrum. Purple isn't the best for them as it can contain uv rays which will age any plants and cause them to die sooner.
