Boiling algae to determine type: red
I believe that it was Paul Kombholtz who recently said.....
>I have noticed that red algae (which normally looks dark green) turns

Well, I boiled an anubias blade with a bit of red algae attached to
it for a couple of minutes. The algae was dark green both before and
after the treatment. It was about 4 mm in length and appeared similar
to what The Optimum Aquarium labels red algae on page 123, item #2.
What gives? Any comments?
My apologies to Paul if the attribution is incorrect.
