Hey dropshort, relax. I'm sure the poster isn't mean-spirited. I, for one, appreciate your knowledge of chemistry and the chemical composition of TSP. I get it. 3 atoms of sodium (periodic table symbol Na) bonds w/the phosphate salt (PO4) comprised of one phosphorous (P) and 4 oxygen (O) atoms to yield the TSP molecule. Chemistry is a wonderful thing.This is the reason I try not to post here. I provided good factual concise information and I get a basketball response.
