    Suction side chlorinator using needle valve

    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...

    Suction side chlorinator using needle valve

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

    My $25 auto chlorinator DIY project

    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...

    Suction side chlorinator using needle valve

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

    My $25 auto chlorinator DIY project

    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...

    Suction side chlorinator using needle valve

    rocketo, did you use the hayward needle valve?

    My $25 auto chlorinator DIY project

    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...

    Suction side chlorinator using needle valve

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

    My $25 auto chlorinator DIY project

    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.

    Life expectancy of a stenner pump

    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...

    Suction side chlorinator using needle valve

    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...

    Removing calcium scale on vinyl liner

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

    Removing calcium scale on vinyl liner

    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...

    Best Method to Aerate

    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 :)

    Removing calcium scale on vinyl liner

    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.

    Removing calcium scale on vinyl liner

    After all the rains my TA has dropped to 50ppm. PH is holding steady at 7.2. I'm contemplating dropping it to 6.8 and spending a lot of time brushing to see if I can get the rest of the scale to release/dissolve, but am wondering how what affect doing so will have on my TA and how long I can...

    Do Kreepy Krawley type vacs really work reliably?

    Thanks. I was hoping more people here used or had used them.

    Alk test won't work

    I think what I'm going to say this winter is you buy it, I'll install it and get you up and running plus help monitor it, and if you end up not liking it I'll buy it from you.

    Alk test won't work

    It'd probably just make him mad :) It's not the money that's the main issue, I just haven't figured out yet what it is.

    Removing calcium scale on vinyl liner

    I ended up closing my pool last season with the TA at 80 and the PH at 6.8. The scale was better this year when I opened, but still present. To date this has been a terrible season with all the rain, so I'm just now getting around to looking at this again. Still trying to determine if just...

    Do Kreepy Krawley type vacs really work reliably?

    I have an older 21,200 gal VL IG pool. Has a hopper deep end with an exit ladder, cut out steps in the shallow end, and one skimmer and one return. Had a main drain in the deep end but it went bad a few years back so I plugged it. With just the one return I am not getting great circulation...

    Alk test won't work

    Thanks all for the input. Pool is now in great shape, water looks like liquid glass, PH is perfect. I'll just keep an eye on it. Swampwoman, that's it exactly. I thought I had him convinced to go SWG a few years back but at the last minute he backed out. It would really be ideal for him, he...

    Alk test won't work

    Thanks. Got the TA up to 150 (overshot on purpose given his sky high CYA and planned continued puck and dichlor use), PH is finally about 7.0. Found some borax so will get the PH to 7.5 and monitor for awhile, because I know he won't. We shocked the heck out of it a few days ago, no metal...

    Alk test won't work

    Added the pool math calculated amount to get the TA up to 100, but this morning it's only reading 50 ppm. Also added sodium carbonate (HTH ph+, no borax around here :( ) to get PH from 6.8 to 7.5, PH still not registering. Plan to add more baking soda and PH+. Would love to see the PH take...

    Alk test won't work

    He did for a while. His pool was perfect. He got tired of manually adding bleach at dusk. Tried to talk him into SWG, he also went for it but in the end reverted back to the pool store and has nothing but problems since.

    Alk test won't work

    Thanks. Baking soda added. Will check TA and PH tonight before I shock and scrub.

    Alk test won't work

    My concern is the PH drop test reads lighter than 6.8 so all I know is that it is low. With the info that if the drop test shows ALK is 0 then PH is really low, like 4.5, it doesn't go up much with the baking soda, and if it doesn't it requires a BUNCH of borax to adjust it up according to pool...

    Alk test won't work

    I've never adjusted a pool this far out of whack. Pool math says if I add 282 oz (12k gal pool) of baking soda TA should go to 100, but PH should only bump .2. If I assume PH is 4.5 as stated above, PM says I need 35 boxes of mule team 20 to get PH back to 7.5. Does that seem right?

    Alk test won't work

    Thanks. Yes on trichlor and dichlor use. He has a bad case of white mold going on, 2ppm FC with a CYA of 150ppm at least. Trust me, I've lead him to the water but he just won't drink. When it all falls apart, I put it back together again, plead my case, and wait for the next time. He needs...

    Alk test won't work

    Found this in the extended test instructions sticky- Sounds like exactly what is going on. I'll use baking soda. I assume the high CYA is the likely culprit?
