What is the difference between Liquid and solid? Im using the pool school calc and want to understand the % difference between the two. The solid from what i see on the canister says 100% Cyanuric acid. What does the liquid contain? FYI, I have a 4545 gallon intex vinyl, swg, shooting for...

this afternoon I put in 4 cups of MA. PH went from 7.5 to 7.1. and TA from 200 to 150. does that seem right. I have to leave it at that till im back in town

Hmmp, May be I have something setup wrong in my calc? I will verify the numbers I input when I get home for lunch. BTW I had to buy 14.5% yesterday to complete this task. no 29% available. Whic means now I have to double it.

well i cant remember the exact amount the calc said approx 16 oz. or so i think? My numbers are at home. I'm pretty sure my PH was 7.8 according to the taylor basic OTO test.

Great Idea on to run the FC/CC test using a 25 ml sample, and multiply by .2. Im going to try that this afternoon. So Just use 25ml water and same reagent amount? or double reagent?

My TA is too High at 190-200, I used pool calc to lower PH from 7.8 down towards 7.1. I have added the correct amount of MA per calc. PH doesnt seem to move much. Should I keep going? My PH seems stable. I thought TA acted like a buffer for PH swings? My TA is suppoed to be at 60-80.

After SLAMMing my pool I have been slowly lowering My SWCG run time to reduce the FC It stabilized around 9 and now Im slowly lowering it. My question is My CC was at 1 sometimes 1.5 before and during SLAM. Now Its is consistantly at .5. Its been .5 for almost 2 weeks'ish. Is that ok? The...

Can someone explain this FC/CYA ratio diffecences? Why does CYA have to be higher and FC lower with SWG? and then, CYA lower and FC Higher with Bleach? with Bleach FC 3-7 CYA 30-50 with SWG FC 3-5 CYA 70-80

Cool thanks for the CYA hint!!

So my SLAM process seems to have gone well. I am now maintaining FC between 7-8 and will be reducing my SWG run time, going to keep it approx FC=5. My CC has bee at .5 consistently. But 1st I believe I need to raise my CYA a bit from 55 to 70.( I kept it lower during my SLAM on purpose, I...

So thanks guys for all the great info you've armed me with. Now family is mad at me for starting the SLAM process when the pool was perfectly clear. I was worried because my FC dropped to 0 then would only rise to 1.0. Is it safe to swim in SLAM water 25:FC? -Once my SLAM process is...

SLAM - Shock Level And Maintain CC level is above 0.5, and the free chlorine (FC) level is zero, started to SLAM the pool. Prerequisites: You need to have a FAS-DPD chlorine test :-D You also need to know your current CYA level 60 ish, and then look up the corresponding FC shock level. :-D...

Great, thanks for info, Im looking now for a speedStir now. That swirling thing may be the issue also. And I did measure CC but not sure how acurrate that was due to my Pink coming back. Will try test again today.

ok, Yes its the FAS/DPD that comes in the TF-100 kit. Like you said maybe I didnt add enough drops to take the test to completion. Because its only a few seconds not 1-2 minutes.

So I have been playing with the pool water chemistry for about a month now. I have been using the K-1000 OTo for quick testing( comes with the TF-100.) The DPD test question: my 1st time doing this type of testing so forgive my dumb question: when I add the suggested amount of powder the...

Where do you guys by your reagents from? Im In AZ but dont mind ordering from internet.

I currently dont have any pool staining. or green hair

why do I want to remove the copper bars? I say you posted this a while back; Many companies fall into the trap of pushing the use of copper ions as an algaecide. Some of it stems from the misunderstanding in the industry of the role cya plays in maintaining proper FC levels. If proper FC levels...

will work on getting full set of test results by wednesday. But yes the swg is intex. and I usually run the copper bars when my swg runs.

anyone else have this build up problem. seems I need to soak with vinager weekly?

I just setup new 18 x 9 52 intex. with 1200 gph sand filter and SWG. I added salt 105 lbs and liquid stabilizer( cyanuric acid) 1/2 gallon. I live in arizona and was wondering when the best time is to run my SWG and test water. The temps here are already 110 :grrrr: :grrrr: . What is the...
