First the green algae, then diatoms, now this purple algae is growing.
It did not grow until after I replaced the T5 light to a 50/50 acetic coral sun marine light.
It is not slimey, I do not believe it is any thing cyno, toxic.
My nitrates are 5ppm
High alkaline
Phosban in sump for silicate control.
30 gallon tank.
10 gallon w/d sump
15 GPD denitrator.
The fish keep it pretty thin. I am curious if any body with high alkaline water has it.
Tank has been setup for only 6 months.
I have no problems with it growing, I am more inclined to cultivate it. For FREE FOOD.
My pseudo damsel elongatus loves the coral.
