I've read several postings recommending that when fighting algae, you should vacuum to waste. I got to thinking about this yesterday while vacuuming my pool for the first time this year. Without getting too verbose on this one, why the recommendation to vacuum straight to waste instead of vacuuming to the filter and then backwashing?
In my (very limited) experience, I lose a lot less water backwashing than I do vacuuming to waste. I also have a very bad habit of being very aware of all the water I'm dumping and rushing the job. Even though my water is very cheap, I still don't like throwing away more than I have to.
