    Muriatic Acid scares the bejeezes out of me.

    Definitely good advice not to pour water into a container of acid. What I'm doing is tipping the pitcher over at the surface of the water, and when the tip makes contact with the water and acid starts to barely pour out, I slowly pushed the pitcher opening under the surface of the water so a...

    Muriatic Acid scares the bejeezes out of me.

    I have one of these I use for the pool. I fill it with the amount of MA I need, then take it to the pool (holding it downwind as I walk), and when I add it to the pool, I kneel down and slowly sink the pitcher into the water, letting pool water fill the rest of the pitcher up, until the whole...

    pH dropped MUCH lower than Pool Math predicted?

    So I finally got the BTB and ran some tests yesterday. I collected a sample of water, and checked the pH + TA. pH was 7.9, and TA was between 60 - 70. I logged 65 for it. I then adjusted the pH with a target of 7.6, assuming 25ppm borates, and the app called for 21oz of 31.45% MA. I added it...

    Jandy Aquapure PLC1400 SWCG scale build up after a few weeks, only on the output "grate"

    Gotcha, I guess I did take it out of context ... for reference, this is to what I was referring ... where you mention the main cause of the calcium scaling is due to the high pH of the water inside the generator. My mistake, and I apologize for any confusion I may have caused. Out of...

    Jandy Aquapure PLC1400 SWCG scale build up after a few weeks, only on the output "grate"

    I think it was @JoyfulNoise who was commenting on it during the YouTube session. If I remember correctly, he even mentioned using borates to reduce the pH rise happening in the cell as a way to mitigate against the scaling. In any case though, it's pretty easy for the OP to set the pump to run...

    Jandy Aquapure PLC1400 SWCG scale build up after a few weeks, only on the output "grate"

    I'm not searching for a problem, just providing some input on a probable cause for an existing problem the OP is experiencing. My comments above are based on information I learned from one of the TFP "meet the experts" YouTube session. Where you guys had discussed the environment inside the...

    Jandy Aquapure PLC1400 SWCG scale build up after a few weeks, only on the output "grate"

    Let's say the pump is running, and the SWCG is set for 30% cycle time. This means the SWCG's electrolysis process is activated for 20 mins of every hour (ie: 30% of the time). So at 6pm, when the OP's pump cycle ends, and the pump turns off ... if the SWCG is inside one of those 20 minute...

    Jandy Aquapure PLC1400 SWCG scale build up after a few weeks, only on the output "grate"

    Ohhh, I just thought of something else. You can alter your schedule to run the pump at some RPM well below the SWCG flow switch, just for say 10 mins, after the normal operation. So 6am - 5pm at 1400RPM, then 5:00pm to 5:10pm at say 600RPM. This way, the SWCG would turn off due to the flow...

    Jandy Aquapure PLC1400 SWCG scale build up after a few weeks, only on the output "grate"

    Just to add ... looking at your plumbing, I would want a check valve here if the pump is not going to run 24x7. If the SWCG is generating when the pump shuts down, you have highly chlorinated water in that vertical pipe. The hot water rises and sits at the top (most likely causing the scale at...

    Jandy Aquapure PLC1400 SWCG scale build up after a few weeks, only on the output "grate"

    Have you considered if the SWCG is generating when the pump shuts off, the stationary water left in the SWCG has altered temp and pH (and CSI) due to the way the electrolysis process works? This could be causing scale to occur quicker than it would if the flow was continuous, or if the SWCG...

    Combination of tabs and liquid chlorine. Ok?

    Go to the TFP Pool School page, and start by reading through the ABCs of Pool Water Chemistry. I've had my pool for a bit over two years now, following the TFP methodology ... and have never shocked my pool ... not even one time. I've never had algae, or any other water quality issue with my...

    VS pump speed - how to determine?

    Aqualink just turns the circuit on or off. The actuator receives the signal from Aqualink, and just spins until it hits a mechanical stop inside (ie: the cam adjustments). So Aqualink doesn't know if the actuator is 100% rotated, or 75% rotated. This is typical of most automation systems...
