I have been backwashing a on regular basis. My sand is also only a year old. I have not tried the deep cleaning process, but, I will if I do not see any progress soon. The 24 test I referred to was actually the overnight loss test. Sorry for the confusion.

I am currently doing the SLAM process on my pool. I had a lot of green algae when the cover was removed. I balanced the pool chemicals first. PH to 7.5, CYA to 70, TA to 70, hardness to 250(nothing added) and slowly brought chlorine level to 4.5 prior to SLAM. I put in roughly 15 gallons of...

Thanks for the advice! I really did not consider turning off my SWG to preserve it's life! That is very good advice and the reason I ask questions! My thanks!

I apologize in advance if this issue has been addressed, but, I have been unable to find any information specific to my area. Let's face it, we do not have hard freezes down here. I normally put a mesh type leaf collector cover with water bags over the pool, run the pump a couple of hours a day...

Received my new board and my SWG is now working like a champ! SLAMmed my pool up to 27 and have been letting it settle back down. After 10 days it has dropped to 10-11.All of my other readings are well within range. Going to start experimenting on SWG run times to keep the chlorine at proper...

Oh yeah, I have been doing that for sure! Thanks!

Just wanted to update my post! After fighting my chlorine levels for a few weeks and after my water warmed up to about 79 degrees, I started noticing that my SWG didn't seem to be working correctly. Lots of talking on the phone confirmed my suspicions that my unit was not putting out hardly any...

Jason, I tried ONE more test of the FSD-CPD. I came up with the 6.5 number again, but, I only added ONE drop to turn it back, so I am at the .5 ppm range. I tried it twice just to make absolutely sure of the number. I thought I might have gotten an extra one in there the first time. We are...

Jason, Yes, I agree with you about the pool math. I am studying it very hard. I used the pool store initially to start adding the chemicals. I had no idea that they would be radically different from what this site recommends. I told them the size and what I had for a liner, SWG, etc., and their...

Jason, I very carefully did the tests again. My FAS-DPD tests came out at 6.5 (13 drops at the 10 ml level) and 1 ppm (2 drops to remove the pink)respectively. I tried the diluted method you described for the CYA and came up with 90 this time. Will the CYA come down over time and, if so, what do...

OK, now I am thoroughly confused! For my FAS-DPD test, I used a 10ml sample. I added 15 drops until the color went from pink to colorless. I then multiplied 15 x .5 = 7.5??? What am I missing? I then added a total of 2 drops of the reagent and that equates to .5 X 2 = 1ppm, right? I also...

Roger that! I will just let it go and monitor. I added the recommended amount when the pool had zero readings for chlorine. Hopefully it will slowly come down and will surely keep an eye on the FC and CC! - - - Updated - - - OBTW! I will NEVER set foot in a Leslie pool store again!

The recommendations I was told for CYA was 60 to 100. I am testing at 96 right now.

Patrick, I did indeed use the 10 mil! Figured it would save some test material!

A quick update of my readings. After adding the recommended amount of bleach and obtaining a FAS-DPD kit. I now have Chlorine readings of 7.25 FC and 1 PPM CC per my test results. Getting some rain here and tons of pollen, so I have let the pump run 16 hours a day to keep it clean. My SWC output...

Oh yeah, donated to the site too!

@Tim! Thank you very much for the info! I will be ordering from them from now on. Love to save $$!

@Tim, Thanks! I have indeed ordered the test kit for the FAS-DPD to add to my kit. I got the 81-330 version. Live and learn! Thanks for the clearing up the ppm question! I guess I couldn't see the forest for the trees! LOL I will post again on this thread when the results are in! I had a pool...

Thank you James! I appreciate the info on the type of bleach to use. My "deluxe" kit was lacking the FAS-DPD test! I am giving up on Leslies! Not much of a choice here in Savannah unfortunately! I wish the "calculator on this site would give you more of an exact reading as far as ppm's are...

Thanks guys! Yes, I have a test kit. The best one that they had at Leslies Pools. Seems to be right on the money matching up against the store tests. My CYA is reading 97. Per this site's calculator I need to add about 2 1/2 gallons of bleach to get my FC to around 6? What does that equate to in...

Hello! I am new to the forum, so thank you for listening! Just got a brand new vinyl liner and decided to switch to a SWG since the water was going to start fresh. I have been slowly getting the numbers right, however, my TAC and FAC are still at 0. Can you tell me if I should go ahead and shock...
