Red ? Algae in refugium

[nobody]

This is growing in the refugium looks to be a redish color (see pics)
Also the usual green algae growing both are only in the refugium nothing in the DT. I did add a white light in addition to the normal grow light a while back , could that be causing it ?
Thanks.

Looks like cyanobacteria

Looks like a mad science experiment but at least it's in your fuge and not DT. Why 2 separate lights? Do you have chaeto growing?

Yes

 

[nobody]

Yes

 

[Lavey29]

Yes

That's good but why 2 separate different types of light?

Agreed why did you change the light? Was it not working out for you ?

He didn't change, he is still running his original gro light but added a second light too which is just white. I see no reason for this and it is obvious why major algae issues are developing in his fuge particularly cyano which really uses light to develop.

If it ain't broke

Yep

I added a second light because since I added it(12-22) it has not grown, it looks nice and green and healthy, just no growth. So I've been trying slowly since then to increase the growth.
I added the white light with a tad of blue and it has started to increase in mass but has developed this cyno problem.

What are you using for your original light? What is your phosphate and nitrate numbers? Do you use a skimmer or reefmat? Algae scrubber?

That could be from iron depleting.

Good point, OP have you tried dosing chaeto gro?

I do, and I stipped for a little while because I thought it wasn't doing anything, then all the algae died in my display, then my chaeto shrank a bunch, and my nutrients went sky high. Started dosing it again at 80% of the recomended dose, and it turned around.

However, when my traces bottomed out I had die off, you aren't experiencing that. So I am not 100% sure

I would say the biggest indicator would be, how are your nitrates and phosphates? If they are well controlled I wouldn't be concerned with growth of the chaeto for a while.

On the other hand, iron depletes rapidly in our systems, so unless you are changing a lot of water out, it might be the culprit.

I use a very pink grow light from amazon, the chaeto looks black wheb its on

Agree but I was asking the OP if he was dosing chaeto gro. I used it successfully also but stopped when I started dosing red sea trace elements.

Woops, didn't even check, I just assumed it was the OPs response, my apologies

Yes I have tryed 2 bottles of cheato gro from brightwell, no change..
Nitrate are 14 and phosphate. 04
I'm not running algae scrubber.
I'm running a skimmer. Tank (90 gal) has been running great since Nov 2019. This is the 1st time I've had any thing like this go on.

The extra white led I added has help considerably with the cheato growth but I guess the side effects are cyno.....hummmm
