Socal, you have us all wrong. We have all seen SO many scams, have had SO many honest but ill-informed pool owners come here and relate the layers of nonsense that they have been fed by pool stores, that I coined the phrase "Pool-Stored" a few years ago for victims who had their pockets picked.
We don't sneer at people who have been pool-stored, we empathize with them. Most of us have been there. And the weapon to fight back against it with is information and knowledge.
If you haven't been taken or scammed by them, that's really great! You are wisely skeptical enough to protect yourself. That's EXACTLY what we encourage you and all the rest of us to be.
TDS is one of their favorite scare-tactics. I had a guy give the whole song-and-dance a couple of months ago about liquid chlorine adding TDS.
Now LC (bleach) adds a particular TDS--Salt. But years and years of LC use won't add NEARLY as much salt as what is required for a Salt Water Generator. A SWG pool has TDS levels that would make a pool store guy positively DROOL at the prospect. But it's all nonsense--Salt as a TDS is basically harmless until there is SO much that the SWG shuts down.
Phosphates are their other big scam so they can sell phosphate reducer. Lately they even are selling phosphate reduction maintenance plans (like you have with your HVAC guys)!
We have found that simply following good, simple maintenance practices consistently works for pretty most everyone. One in a thousand gets into trouble with TDS or phosphates.
