Thank you! No, just backwashing. Worried that will create more issues or Problems with filter ? Is there a time recommendation for deep cleaning? Not sure it’s ever been deep cleaned. Pressure is fine. Hasn’t been above 25% of normal

Day 11 of slam. Not sure if I’m missing something. Water has been clear all along but loses 3 ppm overnight. Brushing daily, shut off swcg 1 hr before checking at night for OCLT and morning test 15 min before sunrise. What else to do? CYA 40 Using slam shock chlorine level of 16. Testing/adding...

pH 7.2 TA 100 CH 260 also update on FC 2.5 (taken mid-afternoon - that's when it does seem to go down slightly) and CC <0.5 (used 10 ml sample instead of 25ml)

Sorry - may have been misleading - still cloudy but less so. At first, could not see 3" into water, now can see third step at 2-3 feet down. Really just want to know a time frame. We would have considered putting off the aa treatment if it was going to take the pool out for this long (have a...

Thanks for the input. We've been wondering that same thing - but why? What would be the 'slightly elevated levels'?

Running out of POP!! (Love that acronym) It has been 10 days and water is still cloudy. Have swg on 100% and able to maintain chlorine level FC between 2-3.8 and CC is at .2 Have had to add muriatic acid to keep pH at 7.2 Just need some reassurance to stay the course.

Whew. Good to know.

Interesting. While I was posting, I left the water sample from the chlorine test on the counter, and when I returned it had turned pink again! Does that mean CC is really higher? Or does it just show that continual chlorination is needed? Too much for a rookie.

Another, or continued, concern: The FC is still 0 on day three of balancing after the aa treatment. Diligently checking chlorine levels: 9am CC 0 1pm CC 0.5 5pm CC 1.0 I've increased the swg to 100% (which means generating 7.3 ppm per day) in order to get CC down. (I assumed more chlorine...

Thank you. Would it benefit us to supplement the swg with liquid bleach - 191 oz per pool calc to get 4 FC - or would it be better to let the swg slowly raise FC - at this rate we don't have any measurable chlorine in the water but do get reading at the returns. We, of course, would like to...

Yikes! help with cloudy water? We are in the midst of ascorbic acid treatment and have increasingly cloudy water. Realizing that this is not unexpected after adding 10lbs of ascorbic acid (5 aa, 5 citric acid) slowly 1 lb at a time, and 2-32 oz bottles of Jacks purple, and starting swcg 2 days...

Another question - if stains are not lifting is it OK to add more muriatic acid to lower pH? PH is 7.2 but was at 6.8 when we succesfully tested with citric acid on a spot....so seems that it might help.

Re: What to do now? ascorbic acid treatment Ascorbic acid treatment now - (actually held the vit c for longer time, tried citric acid powder, and it lifted some of the staining. And kept the chlorine puck on darker stains for 6 hours and so they are finally gone. Patience, patience.....) FC...

Thanks - Added more muriatic acid (a LOT more - 40 oz, then 100 oz, then 82 oz!) aerating in between to bring pH back up. Did this cycle three times and finally TA has moved down to 80. When brushing (with a combo stainless/nylon brush) between aerating cycles, noticed clouds of something...

So - new test results FC 8.5 CC 0 pH 7.5 TA 110 CH 290 CYA 55 Added m. acid, which reduced pH but did not budge TA. (also added cy. acid and calium chloride) Add more m. acid? Water still looks clear, still have the staining/calcium scale/whatever they are?? spots on the bottom of the pool...

Oops I see that if CH is too low it could cause calcium leeching out of the plaster. And it is <2yr old plaster. Preparing to add Morton ice melt - Safe t power heavy duty 100% calcium chloride. Seems very strange to put this in pool (instead of on driveway) so please alert if this is...

If pool is too acidic, will that help remove scaling (if that is what it is). And, could it really BE calcium scaling if the CH is low?

Thanks for fixing the pic! - here's another picture but I still don't think it's the right code?[/url] IMG_1637 by pooldiy, on Flickr[/img] I see from the pool calculator that CH should be 250-350, and it recommends adding muriatic acid (to bring pH down) so -- which to do first? and how will...

No, can't seem to upload pics :hammer: here are recent test results (have figured out how to use test kit!) FC 9 CC 0 pH 7.8 TA 140 CH 130 CYA 45

Neither trichlor nor ascorbic cleared up the streaks. It also did nothing to the dark gray spots. As an aside, there were some small (<1") rust colored spots on tanning ledge that completely went away with the ascorbic acid and the immediate surrounding surface looks brighter/whiter. Wasn't...

Quick answer -not familiar with how to do that...Guessing somewhere on this site has the how-to as this forum just has SO much info. And shows me how much I don't know!

Yeah! passed OCLT: last night/ this am (swg off) FC 19.5/ 18.5 CC 0/ 0 water still clear Will check ph (and do other tests?) when FC is under 10 and vacuum per Bama Rambler's recommendations. The random, shadowy streaks on bottom and partially up sides are still there; there are also darker...

Thanks so much for the tips, confirmations (good and bad) Yes- after sundown, before sunrise: last night/this morning: FC 23.5 / 30 CC .5 / 0 Confirms swg is working! Not so worried about turning off swg since FC level rose with it on last night. So,will try tonight w/out swg and see what...

12.5% sodium hypochlorite liquid 3+ gal (all added 4 days ago) swg is on OCLT (1)Lost 2 FC last night (with swg on), (2) CCs are 0, (3) water is clear - so failed? Leery of turning off swg per OCLT instructions – do not want to worsen situation?! Appears still need to continue shocking? Still...

Nice site….much more info than pool store. Opened pool 4 wks ago for season. Greenish at first but cleared up in a couple of days. Added salt, vacuumed, backwashed filter. In process of shocking (day 4) now per pool store clerk. There are random, shadowy streaks on bottom and up sides –...
