This is supposed to be helpful to the broader objectives of TFP? :(

The broad statement, "algaecides kill algae" is valid which was my point. The rate of killing and differences between species which is correctly pointed out in the article is irrelevant.

Thank you for a sensible response. Except algaecides do kill algae, by various methods, which of course stops their growth! https://www.sciencedirect.com/science/article/abs/pii/S0045653511010654

It is the recommended monthly maintenance dose of the concentrated liquid product for my size pool. Which is what I do as my basis. People here don't seem to understand that. I mentioned algaecide and it was as though I had mentioned kryptonite! I was never advocating its sole use.

Based on your responses here, I would guess that you are not I was relating my own experience which is by definition anecdotal. You responded, and started all this back and forth, with the comment about rapid destruction of quat by chlorine which was providing wider information for which there...

?????

Yes, you are correct. I said so in an earlier post, where I pointed out that I have not run the control without algaecide and my reasons. But you are not me, and as I say above, I would rather not and risk the possibliity, however slight, of another algal bloom and the subsequent work to get...

Thank you for your helpful response. I had many off-site chats with Richard several years ago so I am very familiar with his contributions and knowledge. I am sure if there were any data on the rate of breakdown or decomposition by hypochlorite attack, he would have found them and posted them...

So you are now saying algaecide doesn't kill algae? All the other scientific evidence is incorrect? SMH! Thee is plenty of evidence of its usefulness on this web site. Not just from me.

Thank you for your reply. So the difference between PQ-60 and the linear quats is the rate of breakdown by chlorine? They are both quaternary ammonium salts, and both are effective algaecides with similar killing power. Your analogy with hand-sanitizers is inaccurate in this regard. "Less...

It is certainly not off topic ("algae, chemistry problem"). Algaecide kills algae, that is fact. You mentioned the rapid destruction of the quat by chlorine, which is a chemical reaction (which may have been taking the thread off topic initially) Not having heard this before, I merely asked for...

As I said, I have followed the TFP system, but I add the extra precaution of the algaecide. Now perhaps I don't need to but it is the least inexpensive chemical that I put into the pool, ($25 bottle of concentrate lasts 2 years) and causes no other problems, so to me it is worth it. Admittedly I...

Maybe so, do you have any chemical kinetic data on the rate of reaction with hypochlorite you can point me to? I know from other use in a non-pool case that quats are excellent algaecides, and are quite stable. However, I have had no algae problems since I began using it 9 years ago, and as you...

As well as all the advice given here, I have found that adding liquid algaecide (HTH, quaternary ammonium chlorides) a few times a season really helps and doesn't seem to have any adverse effects. I let my pool guy go years ago after lots of algae issues and with following the TFP system...

After reading all the posts in the EVO thread, I decided to buy the 502. Compared to the 604, I didn't need a 60 ft cord, wasn't bothered about having the two modes (floor-only mode seemed unnecessary to me) and the anti-tangle device doesn't seem to help much. The other difference is it has...
