Thanks for the great education btw. I've read the basics about borates (recommended by you all), and phosphate lowering agents (not recommended, mostly due to expense).
It is impossible to be precise, but can one of the experts give me an idea of how effect these are at preventing algae?
Lets assume every now and then I get lazy or let my FC drop. For example, my kids throw a spontaneous party with a dozen friends. FC drops while i'm at work to zero. etc. etc.
Would dropping phosphates to near zero make it 10% less likely i get an outbreak? 50%?
Would borates be similar? 50%?
Can I get a best guess number?
