    AquaRite 50/50 chance of reporting low chloring

    I have a strange issue. When calibrating the unit there is a 50/50 chance that it reports low chlorine and stops generating. When I look at the schematic for the socket wiring on the AquaRite I see that that there are two channels from the microcontroller each drive a separate relay that powers...

    My experience of time it takes to dissolve salt

    My pool has an in-ground pop-up head cleaning system. The pool is about 11K gallons. The filter is a StaRite System 3. The pump is single speed WhisperFlow and has enough pressure and rate of water flow to operate my OLD Caretaker in-floor cleaning system at 10-12 PSI in the 5-port valve (should...

    Risks of free sodium ions produced in SWCG

    So I've been thinking about SWCG and the creation of free dissolved chlorine and sodium ions. Chlorine as a dissolved gas will, to some extent, outgas rather than sanitize, which leaves an excess of sodium ions which have to go somewhere. In essence if the pool has 3 ppm total chlorine it should...

    Extending shelf life of sodium hypochlorite

    Hi. My local pool supply store has 12.5% trade concentration of sodium hypo for $4 per gallon in 4 gallon totes. I have a SWCG and the liquid is for that occasional shock value during the summer:). I use the super-chlorinate setting on my SWCG during the winter. As with all things, the more...
