My initial pool build design called for an intellichem w/ muriatic acid. The intellichem was just recently released and I haven't heard many reviews about it....PB is slated to order it rather soon. Better to skip it?
Also, found the following quote in the intellichem manual:
"Plaster pools and pools using salt-chlorine generators typically cause a slow pH rise
which must be managed. With IntelliChem, muriatic acid or carbon dioxide (CO2) is
dispensed into the filter system’s return water as needed until the Flow Cell pH sensor
detects the proper pH level. Using CO2 for pH control eliminates the need to handle and
store acid and can be a safer method. As CO2 gas is injected into the pool water, it
dissolves and creates carbonic acid. This weak acid is very efficient at lowering pH with
the added benefit of self-limiting if the CO2 is over-fed."
This would seem to be an endorsement of using an intellichem hooked up to CO2 canister as a complement to the intellichlor SWG.
Searching TFP, I found the following article which seems quite negative about the whole concept:
So, I'm curious what others think....intellichem worth buying? if we do get it, just stick with muriatic acid...I'm not sure how it gets loaded in and whether thats any safer than just pouring acid directly in the pool as needed.
