Ever since I accidentally overdosed CaCl2, my long-term GDA problem has disappeared, and has been replaced by a similar algae which grows only on the glass, looks like GDA, but is reddish brown. It also seems to grow more slowly than GDA.

What is this stuff?

It is, at least, less agressive, less noticeable, and easier to deal with.

Maybe a CaCl2 overdose is a GDA killer?

Could be worth a controlled experiment.

Well, it's not likely the Ca, more likely Cl.
A good scrub and good general maintenance seesm to do the trick
