Does scraped algae reattach to surfaces?

[jjohnwm]

The algae that's now stuck to the poret is vibrant green, healthy as a horse and it's the exact same material that I cut from the plants and hidey-holes last
Whatever kind is common in my old stainless tank doesn't seem to be harmed by getting yanked off of whatever it had been attached to.

Interesting, and I don't think I have ever had that happen except with hair algae. I am forever pulling some of that up here to throw it in there, and no amount of abusive handing seems to bother it. Is the algae "stuck" to your poret pre-filter simply by water-flow, or has it actually re-attached itself to the new surface?

When I "scrape" algae off the front glass, it's that hard/crusty stuff that we used to call "spot" algae. Some of it has a pretty good death-grip on the glass and takes some effort to remove. TB, after reading your post above, I'm going to try an experiment and see what happens; I have an all-glass 40B tank downstairs that is heavily grown on back and ends with spot algae.

Apparently there's something like 7000 species of Green Algae, which is the category into which most of the species with which we deal likely falls. I'm gonna play with the species...seems like only one species?...in that tank.

The results of this experiment will be entirely meaningless in a statistical sense, but will come with a 100% money-back guarantee. Yes, that's right...I will unhesitatingly refund every penny that I receive from MFK members if this fails to answer any of your questions!

It will be interesting to see if the one species that seems more desirable (?), edges out the less desirable "spot" algae.
When I was running a couple tiny sumps, some years back, I would encourage hair algae to grow on lava rock , blocks.



If it got out of hand, I could wad up a ball and feed the Andinoacara


Back further back, many decades ago when I was doing my microbiology studies, we had a text book dedicated to just the algae species of the U.S. Great lakes.
The text book covered over 1,000 algal species from those 5 lakes alone.

I'm not sure as I haven't fondled that block of foam yet but w/out getting my hands wet it looks like it may be re-attaching itself. It definitely doesn't look like it's been harmed by me peeling it off of the plants, wood and rock in the tank. It's been the identical color and look all along.

I guess we’ll find out, I just scraped the back of one of my tanks and put all the algae in my future stiphodon tank to speed up the process
