"Why does he want you do add the muratic acid??? There is no reason to do that considering your test of the water is fine the levels are ok. Don not add that gallon Its only needed in extreme cases of high Alkalinity." Thank you for this answer. I didn't understand why he was asking me to add it, your answer confirms that I am not going to do it. I am going to try and get the manager of this campground to arrange education for us about pool maintenance. Neither one of us have done this before this campground. He's been doing this a couple of years, though, and mine is a matter of months. I'm reading everything that I can get my hands on, and asking questions. "Also shock your pool since your CC reading should be 0" I will do that. Thank you.

I help maintain an 18,000 gallon semi-private pool. This is at a membership only campground. In the last 2 days I have had a problem with the water clouding so badly that I cannot see the drain in the bottom of the pool. My boss and I are really baffled about this. We use Taylor's K-2006 test kit. This is what happened and what the test results were: Sat 8/11 8am Free Chlorine 5.0 Combined Chlorine .4 pH 7.0 Alk 100 Calcium Hardness 230 CYA 36 TDS 620 Temp 84.2f I added 23 oz soda ash to raise pH level. The pool looked great. 4pm Free Chlorine 2.2 Combined Chlorine .2 pH 7.3 I did not test the others. We usually don't in the afternoon. Just the Chlorine and pH. I added 1.1 lb soda ash to the pool to raise the pH. This caused the pool to become so cloudy that I could not see the bottom step of the pool in the shallow end. I then cleaned the 2 next to the pool filters and socks, cleaned the in-line filter basket and back flushed (we have a sand filter). I also added 3 oz Super Clarifier. By 7:30 am the next morning the pool was clear and beautiful. 8/12 7:30am Free Chlorine 4.8 Combined Chlorine .4 pH 7.3 Alk 110 Calcium Hardness 240 TDS 632 Temp 83.9f I added 23 oz soda ash to raise the pH (I have since found out that a pH of 7.3 is fine and I don't need to do that). The pool became cloudy again. There was no need to back-flush (the psi was 13). Neither my boss or I know what is causing this. He thinks that it might be metals in the water, I'm wondering if the bottom drain might be clogged (the next-to-the-pool filter baskets are clean, as are the in-line basket filter and the sand filter, and the test results are within range). Does anyone have any idea what is causing this, and/or how to prevent it? Added: This also happened 3 weeks ago and we took the same steps that I took on 8/11. Also, my boss wants me to dump a gallon of muriatic acid into the pool tonight about 10pm. Thank you. Terri Seaview, Washington
