We operate a 22 story office building. It has two chillers and a looling tower. we have recently installed a new chemical feed system and controller (high tech might i add) and our water quality company has instructed us to use chlorine, molybdate, and a biocide. Is the chlorine necessary? We have been keeping it at about .5 ppm to 1.0 ppm and still have algae growing on the cooling fins and in the resevoir. Also what is a good way of controlling ORP (oxidation reduction potential)?
