"Taking a stab in the dark but...
Is this pool's skimming system working properly? Organics tend to float and body oils definitely float. If the skimming system is not working well (or at all) then its quite possible to have an organic soup near…"
"I think your analogy of gasoline consumption to chlorine PPM is a bit off. As long as pH is controlled properly there isn't much change in sanitizer residual (assuming the feed rate is capable of keeping up with demand). I would suggest that…"
"Another part of the ORP/Residual problem has nothing to do with the ORP controller but rather the people performing chemistry tests and the testing reagents themselves.
In almost every facility I've been to in the last 25 years people…"
"ORP control can be very confusing and frustrating if you don't really understand what ORP is and what the sensors detect.
PPM Sensors actually detect chlorine while ORP sensors have nothing to do with chlorine. ORP Sensors measure the…"
"Why 88f? That is high for indoor never mind outdoors.
I'd say open the pool when the outdoor temperature is high enough that heating won't break the budget. Do you have any solar or geothermal heating or is it purely electric/gas heat?"
"That's what the facility was looking into as a trial last time I talked to them. Not sure what brand they chose.
After talking to a few folks and examining their experience I've revised my conclusion. I think the brand they purchased just…"
"That can happen in otherwise well run pools. A private facility I visited had their gas chlorine system break down and had to run manually for several weeks. At the same time the health authority was all over chloramine levels so guarding staff were…"
"Did the site visit and it was a bit different than was described to me. The site formerly used vacuum DE and they kept the tanks to use as surge tanks and to let them switch back to a vacuum system should the regenerative filters not live up to the…"
""make usre you have the right amount. Add half, or less, of the calculated amount,"
Words to live by. Any time I'm making additions to an new pool or one I haven't made additions to in a long time I…"
"Pools designed for salt rarely have issues with it but retro-fitted pools can have pretty big issues. Salt pools are still just chlorine pools, the only difference is you electrically "crack" salt to get chlorine rather than use gas.…"
"I've no experience myself but I'm heading out to a facility that has problems with a regenerative filter setup. I'll get more details later from the horses' mouth but I gather that body oils are plugging up the septum screens…"
"I find the biggest problem is not sensors going "dead" but rather getting too slow. Signal magnitude can be almost perfect but if the response to chemical changes is too slow you end up over and undershooting (pump too fast or two slow…"
How is everything with you, I picked interest on you after going through your short profile and deemed it necessary to write you immediately. I have something very vital to disclose to you, but I found it difficult to express myself here, since it's a public site.Could you please get back to me on:( email@example.com ) for the full details.
