cloudy pool

Yes, the CYA re-do will drive everything, so take your time and re-pour the solution back & forth to the viewing tube as much as needed to get a good number. If it is indeed below 30 (black dot visible when filled) then yes, add some stabilizer for a new CYA target of about 30. Whatever you determine your new CYA to be (re-test tomorrow), adjust the FC SLAM level to match as noted on the Chlorine/CYA Chart. Example 30 CYA = FC of 12; 40 CYA = FC of 16; 50 CYA = FC of 20, etc. Hopefully it's a bright sunny day where you live for a good CYA test.
 
Hi Brian,

I can attest to the success of a proper SLAM. I tried to review your whole thread and if I understand correctly, you started this process Wednesday. I know from experience it can take a lot more that 4 days to completely clear up a good cloudy algae outbreak.

Once it does start to clear, please pay special attention to brushing hidden areas and crevices to keep any algae bloom at bay. I've found algae in the frames of the skimmer boxes and in crevices around our steps. We don't have ladders but taking those out and cleaning may be necessary if you do have them.

I think you are on the right track from what I've read. Keep pump running 24/7 and please try to post up a picture daily. I don't think 4 is enough to feel set back or throw in the towel.
 
Of course, it is sunny FL!! We have liquid stabilizer will add according to pool math. With liquid can we retest cya in a few hours or should we wait until tomorrow? Since it is doubtful we even have chlorine in the pool, I checked the PH it isn't even pink, it is purple. My fear was turning the spa/waterfall off for 23.5 hours a day causes my returns jets to have outrageous flow and rippling the water. If bleach has alkaline which raises the Ph, with no stabilizer in the pool, will the lack of stabilizer make a the bleach and alkaline breakdown or just the bleach? I would be able to sleep better at night if you tell me to add acid and get the PH down

Is it cloudy at all with the pool water + CYA test solution?

I really don't want you to go too high with the CYA. Pretend it is a CYA of 10 and add what Pool Math tells you to add to get the CYA to 30.

With the pool being screened in that will help defuse the sun.

Keep adding chlorine in the amount you were adding before you ran out of regent to get you to SLAM level. Keep brushing as well. This really helps get the stuff up for the chlorine to kill and for the filter to get ahold of and filter out.

You can also add an old T-shirt to your skimmer basket to help the filter. It will be a pre-filter. Just make sure you have a good flow of water to your pump.

We had a sock on the skimmer, our pressure is so strong it sucked it into the pump. Our filter is immaculate, I clean it everyday as many times a day as it needs. We have been adding 1/2 to 2/3 of everything recommended on pool math except bleach we use full recommended amount. As far as previous slam level, if I have no cya was I ever in SLAM? Can we lower the Ph to about 7 or should I quit wiggling out about the ph. Just some info we raised our PH from 7.5 to 7.6 just from turning return on in spa for 1 hour.

Well no more sucking stuff in to the pump! OUCH!

I think you should go buy one of those drop kits from Walmart or such. Get some distilled water while you are there as we KNOW it does not have any FC in it.

We are going to do half distilled water/half pool water to find your FC +/-. It is not the best way but it is better than nothing at this point. We will work on the PH

It is funny how cameras and different computers all make the same picture look different. That is why I try to always look at pics on my laptop as that is my primary computer.

:hug: THANKS so much for becoming a supporting member. It made my heart smile!

Make sure to take the picture at the same spot tomorrow. Is this looking down at the steps? If not put your brush in so you can watch it clear up bit by bit.

We have cleared pools where we thought for sure the Creature from the Black Lagoon lived there!

Brian,

There's plenty of cooks in this broth so I will simply remind you that SLAM is a process and it involves running your pump 24/7, brushing often and doing EVERYTHING in the SLAM article. Reread that article and make sure you understand every aspect of this process.
 
Again, good news and bad news. Good news we are seeing slight clearing. Bad news is we strongly suspect the number of gallons pool holds is incorrect per previous owner ( not the original owner). Last evening we were told to assume our CYA was 10 and goal of 30. We added 2/3 of what pool math recommended, knowing we had to slam and didn't want it going above 30. Tested CYA last night 4 hours after adding liquid stabilizer and we were reading 40. Kim suggested doing our CYA today (time for stabilizer to distribute) we did, our CYA was 50 (zero doubt on the results) We did the test independently and held the tube at different distances to our face.....no black dot, not even a ghost. (Plenty of sun our backs to the sun). We decided to check the CH to see if we had enough to allow for a partial drain to get our CYA back down to 30. When we did the test, after adding the r010 clear..... good Then we added the R011 it turned light pink, so far so good, Then we added the R012 one drop at a time swirling in between, 3 drops turned basically clear with a very slight pink tint along the top where the bubbles are one more drop rendered no color change. At no time did we see any color that resembled blue or purple. We never got this on our previous CH tests. We have done this 6 or 7 times, same result. We decided something had to be wrong. Tested again, same thing. Decided maybe something was wrong with our reagents. Purchased new ones, redid the test, same thing!! Found information on TFP regarding CH test one of your experts suggested referring to I think it is Waterbear.....we found that reference and did the test 2 times swirling well as recommended and we are still coming up with the same thing. What is going on?
What do we do if our CH is very low, being told previously by Matt, that you can never add calcium to a cloudy pool, or during slam.
 
Let's address each issue:
- FC/CYA (SLAM) - now that you've confirmed CYA to be 50, increase FC to 20 and continue the SLAM. That's priority #1.
- CH - When you added the R-0011 drops, I'm assuming you added the required 3 drops correct? Turning pink we know you have "some" calcium. Then when adding the R-0012, you wait for it to turn blue. Are you using a magnetic speedstir? For CH testing, it helps a lot to swirl the sample quickly and consistently. For me, I have a hard time seeing the color change. It's a subtle blue. Sometimes tough to pick-up on.

In any case, focus on the SLAM and completing that first, then we can re-address the CH.
 
Since you suspect your CH may be low, have you tried this:
If you expect that your CH level is very low, you can do the test so that each drop is 10, instead of 25, to get some extra precision. Use 25 ml of pool water, 20 drops of R-0010, 5 drops of R-0011L, and multiply the number of drops of R-0012 by 10 to get your CH level.
