We've had a large in ground pool for about 10 years. We have a heat pump which just broke. We've had a technician look at it, but he doesn't have a clue what it will take to fix it yet. When we built the pool, we plumbed pipes in to run water to our rooftop. They are capped at ground level, and...

Hello. I've had to SLAM our pool in the past and it worked. Now I'm not sure what is going wrong. We are on day 18. Our CYA started at 60, so I've been getting the FC up to 24 and then letting it get as low as 14. We are adding liquid chlorine 4-6 times daily and have added more than 200...

Typically it is just rain water

Hi all. I'm constantly adding muriatic acid to our pool to reduce the PH. That being said, since 5-30-21 until today, I've gotten the TA from 180 to 90. It's taken me about 15 gallons of acid to get here. Is that to be expected, or is something wrong? PH 7.8 Chlorine 2 TA 90 CH 480 CYA 35...

thank you!

I have a chlorine pool, not SWG. I thought I could use softener salt for the Calcium. If that is wrong, what would you suggest I use? I added chlorine just after the tes tlast night. That was dangerously low! Thanks

FC .5 PH 7.2 TA 190 CH 130 CYA 35 I dumped 5 40 pound bags of water softener salt in 5 days ago. In addition to the brass corosion above, any idea why my CH would still be so low?

I can get an updated set of test results tonight.

I put my hose in the water for 2-3 days to fill the pool. It was not running the entire time, but nobody pulled it out when it was not running. Once I pulled the hose out of the pool, it came out looking like this. It appears to be calcium, but I didn't taste it. Any ideas why this would happen...

Thanks. I know TF ships fast. Hopefully those will come in a day or two.

Hi guys. I've been diligently testing, adding chlorine, and scrubbing the pool. The green is mostly gone and now it is pretty clear. Still not sparkling clear. I've spent over $1000 on 10% sodium hypo liquid sanitizer, and used about 2/3 of it. 2 questions- Would it help if I left the solar...

Thank for the education, guys. I did an overnight test, and it looks like I will be performing a SLAM.

I'm using a TF 100 test kit. Does it need slammed if the chlorine is holding steady now?

Hello. fr about 10 days, I've been battling algae. I've been scrubbing and using our robot daily, and have been progressively riaing my CL to about 5 now where I'm keeping it. In the first few days, I was losing and the CL would be at 0 or .5 and I would bring it back. The CL seems to be stable...

Thanks for help figuring out the concentration of bleach. I now wish I had stayed up another 30 minutes last night and done another test. OCLT results: FC 16.5 CC 0 I believe the volume of water calculation to be correct. We've had the pool completely drained and refilled, and both times the...

Nobody swam today, and the pool cover was on all day. After sunset, I did a test. FC 3 CC .5 I added 425 ounces (3.5 jugs) of 7.86% I waited 35 minutes and tested again. FC 7 CC .5 ChemGeek- does this mean that the chlorine is not really 7.86% Would it be about half that? I added an...

The readings above were from last night. I added enough bleach to take the FC to 10.5. This morning, I was at 7.5 FC, and 0 CC. I spread 121 ounces around 60% of the pool, and left the pump running. 40 minutes later, I tested again. I was at 8.5 FC, and almost (it was a very light pink) .5 CC...

I disconnected the ozonator last night around sunset. This morning, my FC tested at 5 (CC .5), and I added 363 ounces (almost 3 gallons) of 7.86% bleach. This should have taken our FC to 10.5. The pool was covered all day. Nobody swam in it. It was sunny, and my solar cover is clear. I ran...

We are in full sun all day. We keep the cover on except for when we are using the pool, but it is a clear cover. Does a colored cover really reduce chlorine consumption?

This is another possibility. Doesn't bleach lose it's effectiveness over time?

I've turned off the ozonator, and would love to get to the point of only using 40-40 ounces daily! Even double the with more swimmers would be ok by me.

Thanks for the knowledgeable comments. If I change my FC target to 6, and still lose 3.5 per day, do I end up growing algae at that level- or even lower if we have a lot of swimmers on a sunny day? I also appreciate the comments on the SWG. I'll be doing more research on this for next summer.

I work hard to keep all leaves and debris out of the pool. Of course, the winds do blow, so we do get stuff in there, but typically I, or our automatic pool cleaner get it out ASAP.

I like this idea. Let me run it by the wife...

I'm buying 7.75% bleach from Wal Mart. It's under $3 for 128 oz. we are also swimming lots. 4-12 people in the pool each day. Sent from my iPad using Tapatalk

This is our 2nd year with a pool. The people on this forum have helped turn my green pool into a crystal clear pool both summers. I'm very grateful. I also feel that next year I will have a much better understanding of how to not let my CYA get too high by using chlorine bleach instead of...

Thanks to all of you, I can count the holes on my drain cover, and even see the stairs all the way across the pool. Thanks!

I do have wedding cake stairs, 2 ladders, and a light. I thought the very high chlorine levels for such a long time would have killed everything alive in the pool, and the CC being at 0 for so long was proof of that. On the other hand, I'm still using quite a bit of chlorine. Other thoughts?

Still struggling. The water is crystal clear. Beautiful! I started the SLAM 9 days ago. Due to the high CYA, my slam # (FC) is 31. We ran out of reagent after 6 days of SLAM, and still dumped a lot of chlorine in the pool, but I can't say exactly where my FC level was. We got more reagent...
