True, but I run my pump 24/7 and my daily injection would only be 60 oz, so a very small dribble that should have a really low impact. Also, as pointed out, Mark uses a similar set up for acid injection and hasn't noted any low PH problems. - - - Updated - - - Thanks. I've been through that...

Thanks, but to be clear, the system I was talking about was for sodium hypochlorite injection, not pucks or dissolved di-chlor.

Actually I wonder if injecting it into the return side might not solve the suspected problem. I suspect return flow would possibly create a slight suction affect but not near what the suction side would. Wouldn't even need to run the line to far into the return. Hmmm...

Ok, thanks. Yeah I tried that one too, no go. I've got the hayward, so I guess I'll try it.

Took me a few reads but I get exactly what you are saying. That's actually pretty ingenious. Only issue I'm left wondering about is it's about 20' from where the pump will be to the skimmer. Will the drop pump push chlorine this far? I'd also have to get creative for how I can run my vacuum...

rocketo, did you use the hayward needle valve?

Thanks. All of the chlorine resistant solenoid valves I've found are very expensive. Peristaltic pumps are about half, and the idea discussed in this thread is about $40 for the install, making it very attractive. I had though of setting it up with the line into the suction side of the pump...

Thanks. Bama, I wasn't aware you were using it with a liquidator. I have the valve, I guess I'll experiment with it.

It seems you 3 all have AG pools. I'm wracking my brain trying to figure out how to make it work with an IG pool. I could inject into the suction side of the pump, but no idea if the suction on the pump would cause an issue or not.

Digging through years of old threads looking for info on the hayward needle valve chlorine injection I posted about, I found gobs of info and mostly praise for the Stenner injection pump. I like the concept (and pricing :) ) much better than SWG and think it may be ideal for my and my dad's...

Several years back there was discussion about using a fine needle valve threaded into a container with hose going from it to the drain plug on the suction side of the pump. I think Hayward made the valve that was able to be closed enough to allow adjustment for our use. I bought one, and never...

Interesting, thanks. However the scale covers probably 60% of my liner, that would take a lot of time. Plus, PH already dropped :)

Ok. I'm probably just gun shy from dealing with my dad's 0 TA pool the past week. Didn't want it to crash. Any guesstimate how long I should have to leave the PH low to get it dissolved? I plan to brush the heck out of it over the next several days, as much as possible. I did notice last...

I could never get aeration to work to get my TA down prior to PH rising and requiring more acid. What I do now when it's needed is add the acid ahead of rain. Rain is the supreme aerator. And it's free :)

Perfect, that's what I wanted to hear. I think I'll adjust my TA up to 80 to give me more of a buffer then drop PH to 6.8. We aren't supposed to get any more rain for a few days, but if we do this will give me some room without crashing TA if it does. Rain is a great aerator. Thanks.
