Ulva Growing on Screen

[PlantationMark]

I have Ulva growing on my screen. Is that a problem?

I mean, it's dominant!
I get about 2 handfuls per week off it.

Problem is, it's growing all over the Display, too!
Also throughout the Display is red bubble, caulerpa, GHA! And new to the party green bubble algae.

Nitrates at zero (down from over 100 just 8 weeks ago).
Phosphate at about 1-2
Should i be patient and wait for it to die off?
I know my screen isn't cactus rough, i've got to get out in the garage and work my spare sheet.
I was expecting GHA since it grows well in the DT, but other than Ulva i'm only getting slime on the screen.
Also, the green algae on the display glass needs to be cleaned every day . . . it used to be every 3 days.

Any advice? Thanx!

Without investigating further... you have a scrubber in your display. You need to physically remove display algae so as to weaken that scrubber; reducing display lighting will help too, as long as your actual scrubber is still growing green.

Not at all
