For a little more background, at the start of the pool season the pool was green and filthy. The pool was uncovered last winter and had lots of leaves etc. in the water. My son first got in with waders, scooped, vacuumed, backwashed etc. multiple times then added lots of liquid chlorine...

I added 1.5 boxes of Borax to get the PH up to 7.5 and the TA measured 70ppm (didn't add any baking soda). The FC was at 8.5 ppm and the CYA 40ppm. There may be a very slight improvement in the water clarity. I think I can just barely see the bottom of the pool's vinyl pattern. Does...

27' diameter, 46" water depth estimated at 18,500 gallons. The CYA is 40ppm, using a standard sandfilter and liquid chlorine as already posted. Headed to the store to get borax, baking soda and make adjustments. Will post new reading when complete.

Originally the CYA was at zero so we added 2 gallons of liquid stabilizer to get the CYA to 40 ppm. While waiting to receive the Liquid stabilizer we used tricor chlorine pucks to get some CYA in the pool. After the CYA was at 40 ppm we switched to 10% liquid chlorine. I know the pucks will...

I'm helping my son try to clear up his pool water. He has a 27' above ground and the water is too cloudy to see the pool bottom. We have had it up to shock level FC or above for about a week but little or no improvement in the cloudy water. We use a TF-100 test kit and the CYA is at 40 so we...

My son is trying to get his above ground pool (about 19,000 gallon) cleared up after the winter. He just had it in shock mode for a few days and the water is looking much better compared to the "swamp" he had last week. The water is still somewhat cloudy but last night he passed the OCLT test...

Hello, Just opened the pool for the third season after having it installed. It's a vinyl 18x36 but the problem is with the ladders and the ladder "sleeves" that they slip into. The sleeves are embedded into the concrete deck and they have a crusty buildup that makes removing and installing...

I'd like to get some clarification on how to read the view tube on the cya test. As an example when looking down the view tube I often think the black dot has completely disappeared. But after a few seconds I may start to see a very slight shadow where the dot is. (like I can see it and then...

It is cloudy but we would be able to see swimmers even in the deep end.

I just checked the FC level again and it is at 7.5 and the CC =0 or at most 0.5. This is up from a level of 5.0 this morning because I got up briefly from my nap about three hours ago and added 121 oz of 8.25% bleach. I also should memtion that on sunny days like today we get sun all day long...

Well I just got up since I work a 12 hour night shift. Thanks to all for the response. Because of my work schedule I can't do an OCLT until Sunday night but I can bring my chlorine level up. I just can't stay up all day testing and adding bleach. I have about three hours to tend to the pool...

I forgot to mention that my CC =0.5

First let me list my test results from this morning. FC = 5.0 PH = 7.5 TA = 100 CH = 100 CYA = ~42 The water has been very clear since pool opening on 5/4/15. The test levels have been consistently around where they are now. Yesterday I noticed the water was starting to get a little cloudy...

Agree completely with the advise to slow down. Not the way I normally do things. I'll make it a priority to add Muriatic Acid tomorrow and shoot for a ph level of 7.6. Thanks, Dave.

After adding the four boxes of baking soda yesterday to raise the TA, I found the PH was up also to about 6.8. Since that's still too low I added three boxes of borax (20 mule team 76oz) and measured ph again. The ph reading was about 7.0, so I went to the store for more borax and added two...
