Hi Brian, thanks for the video! Looks most ingenious and effective. One question: is there a concern with acid building up in the pump by diffusion when the pump is off, and then either damaging the pump or creating a blast of acid when the pump is turned on? Perhaps the length of tubing you have between the acid container and the pump mitigates this.
@@sgo60 I did notice a little acid moving when the pump was off. I had no damage after running it for a year, but I didn’t like seeing that. I have since installed a fairly expensive heavy duty acid valve ($140’ish) in between the needle valve and the pump. It’s a solenoid valve, always closed. I have it wired into my pool controller’s AUX circuit. I now run it like 10 minutes per day at a higher flow. I made a video, but I haven’t uploaded it yet.
@@sgo60 My guess is if your system is perfectly sealed and air tight, it'll be fine with the valve. Somewhere I had a little vacuum drawing the tiniest bit from the tank since that's the weakest link of the system (check valves everywhere else downstream of the pump). Similarly, I always purge some air bubbles when my system first fires up. The valve prevents flow, just like sealing the top of a straw.

@@UraniumTwoThirtyFive Thank you. That addresses the concern.
