Yellow Rid is...well, Arch considers its chemistry a trade secret but it's deadly poisonous and decomposes into ammonia and sulfur trioxide and is listed as incompatible with: "Other pool treatment products, strong
oxidizers, bases, chlorates, nitrates, chlorine or bromine compounds".
Ammonium sulfate or ammonium chloride. If you follow instructions, you'll create a chloramine (CC), "monochloramine", which IS an effective algaecide, but also is irritating and hard to get remove -- requires LOTS of chlorine for clean up.

Phos Free ... Nobody will say what's in it...just that it's "natural" and "non-toxic" and, of course, patented. They even warn that water can go cloudy!
Lanthanum chloride or lanthanum something else. ALL of the phosphorous removers are based on lanthanum something or other, and precipitate lanthunum phosphate, which you then have to filter out.


No More Problems ...seems to be an algaecide, probably ammonia-based, mixed with some kind of chlorine--probably Di-Chlor. Another "Patented Secret Formula!"
Like almost all of United Chemical's products, No Mor Problems is based on sodium bromide. Many UCC products also contain sodium hexametaPHOSPHATE, which helps penetrate algae layers (NOW) and adds to your phosphate later (LATER).

Your dealer probably didn't know it, but he was selling you products to REMOVE phosphates AND products which ADD phosphates.

Sort of a racket . . . even when it's unintentional!
