It's got to do with energy. The principle of conservation of energy is that energy cannot be created nor destroyed, it can only change state. Water flowing through a pipe only has a certain amount of energy packed into its pressure, velocity, and temperature. If any of these three properties...

Re: ORP values have never really correlated with the Cl valu Topics merged. JasonLion I elaborated a bit on that in a different thread. This was meant to show the relationship between pH and ORP and PPM FAC. The exact numbers are NEVER the real numbers but sufficient when talking about these...

Re: Need feedback on my proposed Stenner solution You can put the injectors quite close and feed at the same time without problems IF, and ONLY IF, you make sure chemicals cannot feed if there is no flow in the system. In my pools I place the acid/soda ash injectors first and the sanitizer...

Understanding ORP is the single biggest problem I run into when dealing with new staff. It's not a difficult topic but nobody really offers any training on automated controllers the way training is offered for manual chemistry and pool operation. First ORP doesn't have anything to do with...

I still have three AK100s running and can answer almost any question (depends on firmware version etc). I've got manually around here someplace and the online manual is also available.
