My opinion is that most folks use algicides as well as bleach to keep their pools from turning green and I’m not sure I’d trust any filters to remove the algicides. …
The one thing I do know for sure about the black Berkey filters is that they aren’t just filled with activated charcoal like some filters (like the Brita filters.) Here is part of a FAQ I found on the filters:
http://www.bigberkeywaterfilters.com/he … urces/faq/
What are the Black Berkey elements made out of and how do they work?
So while it’s probably safe to drink pool water filtered by a black Berkey filter, since it’s not listed I’m not willing to risk it in all but the worst circumstances. I’ve got access to a river and other water sources that aren’t treated at all that I do trust the black Berkey filters to work with.
But if the pool water is your only source then you have to weigh the risks unless someone can find information that it will remove the algicides, or that there is another filter that says it definitely will remove them.
Well, I was making the assumption that the inquiry was discussing using pool water in an emergency, and I guess I am to be faulted for making an assumption…
That said, I have some basic chemistry background (on par with a year of normal college chemistry) and some dealings with public policy. Based on the fact that these algaecides are approved to use in pools and that most pools get drained into the environment, the chemicals are not likely to be too dangerous.
I did a bit more research, and found this:
http://www.poolproducts.com/blog/pet-po … icals-pets
Algaecides, Antifreeze and clarifiers are not considered harmful when they are properly diluted in the pool water. When they are not diluted or broken down into the water they are corrosive and dangerous.
The article is discussing pet safety around pools, and while they warn several times about the chlorine, this is saying that algaecides are not dangerous in moderate amounts. OTOH, if you are drinking out of a pool for several days, you are ingesting a lot of this water.
There is a good resource (for a lot of stuff about water) here:
you can see his qualifications here:

(Note the HTTPS in his address – this guy seems “kinda serious”)
The author specifically addresses pool water here:
https://omegamanjournal.wordpress.com/2 … ing-water/
and there are links from that article to several other of his articles.
If you plan to use pool water as a primary back up, I would recommend reading all of the linked articles too. (Frankly, I plan to read all of them, just because water is such an important subject.)
