Dealing with black algae (Part 1 of 2)

[smallpooldad]

Chem Geek,

You are correct on both your assumptions. The black algae, more properly known from reading further, as blue-green or cyanobacteria, as far as can be seen, stays "glued" to the plaster and yes I did try the scrubbing method without great success. See article on it here maybe we can sell it to NASA to grow on the moon as described in external links at end of article.

So I suppose it must be made of stronger stuff. We have a saying here "Hawaiian Superman" maybe this is "Hawaiian Super Algae" and no I am not originally from here. The type tested in 1980 must be the "Weak Little Haole" type aimlessly floating around; true according to my wife. For information Haoles translate to puny white people, like me, originally the truer Hawaiian translation meant foreigner among other things, but nowadays it is used mostly as a joke and even as a term of endearment, although it can be derisive, as in "Stupid Haole", not very nice but it helps white persons like myself realize how bad and sickening racism is. Maybe we could sell your type as a pet!

A more complete description of the history of the word Haole can be found here:

Mustard algae has not been a real issue on this side, the south, of Oahu although I am told it can be prevalent on the North Shore, why I do not know.

After writing this I had a thought, would not the BBB method work better? It did work well for me for a number of years albeit time consuming.

For those of you that have the time, staying at home most of the time, the answer might be yes. But if you work or travel and your time is not always your own a Salt Water Generator is, to my mind at least, the way to go; it consistenly outputs the correct amount of chlorine.

If one has a digital controller for the acid (highly recommended) the daily tasks of checking can be skipped occasionally; giving piece of mind if one is unable to attend it, again for those of us whose schedules are controlled by others or events.

As always thank you for your reply and knowledge.

PS. If you have any scientist friends here let me know as I know of a pool that has a plentiful supply of the "glue" type. Why because he actually believes his pool person can get rid of it by diveing and scrubbing at $150 an hour! And yes he's a Haole, worse still he comes from the same country I do originally; and only 3 miles from where I lived. Please, please don't tell the Hawaiians, I don't want him and me to end up like Captain Cook.
