is this accurate? for me, the cheapest i've found acid at lowes or home depot is $10 for two gallons at lowes, but it's the half-strength stuff. leslies sells 2 gallons of full strength for $17, which makes them a better deal...The only chems you will need are pretty basic. Muriatic acid for adjusting your pH and liquid chlorine that you can get at Lowes, Home Depot or Walmart... stay away from the pool stores.. the prices are usually jacked up for the same product elsewhere. .
Prices vary in different locals. in the Sacramento area i can get a gallon of 10% for about $3.64. My local pool store sells 12.5 % cases (4 gallons per case) for $23... its cheaper by concentration to get the 10%.. if the prices change I always recalculate.is this accurate? for me, the cheapest i've found acid at lowes or home depot is $10 for two gallons at lowes, but it's the half-strength stuff. leslies sells 2 gallons of full strength for $17, which makes them a better deal...
nice, that's what i was getting at (acid is the one thing that might be cheaper at the pool store). what pool store is that?Hey Crackers! update.. I see you were asking about ACID. I get that from my local pool store in a recycled bottle (I return the gallon jug) for $6 a gallon. that is for good stuff (31.45%/20 Baume)
awesome, thanks! i would assume i'm looking for the "deposit acid" case, not disposable...right? normally i just get my acid at leslies (since like i said it's full strength and more cost effective than the half-strength stuff at lowes or HD), but as far as i know they only have the disposables. deposit/return isn't an option there...Its a family owned local pool store. They happen to be a seller of HASA products that sells the higher concentration Chlorine and MA. I have seen it at some Leslies stores.
Try this in your area... I don't think they get the small shops but it will get you in the right direction

Thanks. I will. I forgot to add CL one day.You must add chlorine EVERY DAY.
A CYA of 20 is way too low. Get your CYA to 30 or 40 until you pass the SLAM Process criteria and then raise it to 50 ppm.
Lower your pH to 7.6 with acid. Test it every day or every other day. Add acid to lower to 7.6 when you test it at 8 or higher. Test TA weekly to use in Poolmath for acid addition calculations.
CYA helps protect the Cl from the sun, otherwise the UV breaksdown the chlorine. The 30-40ppm level is what we have found works best in a pool chlorinated with liquid chlorine. Otherwise you will lose all your chlorine to the sun. .. Later after you SLAM you raise it to 50.. that works best in the sunny climes of the south west.Thanks. I will. I forgot to add CL one day.
Regarding CYA: can't I keep the CYA at 30 or 40 instead of 50? And why the CYA of 20 is not recommended? Also, what is the best way to increase the CYA?
Regarding pH: I tested the pH last week or so with another test kit and it was 8.0 and I added MA to lower it to 7.6 based on the calculations in Poolmath. I assume the pH of the freshwater that is added daily to the pool should be around 7.5. My pH increases to 8+ in 7-10 days. Why does the pH go up? Do debris/leaves increase the pH?
Any comment on Q4? I have read that people say avoid Clorox. Not sure what products!A few questions about the SLAM process
1) The water is very clear and I have no signs of algae in the pool. In the spa however, I can see a bit green (prob 2 in x 2 in) at 2 corners of the walls. Do I still need to do the SLAM?
2) Should I start with clean filters? Again, the water is not green.
3) I tried to reduce the pH as recommended above. Poolmath said 123 oz to lower the pH from 8 to 7.6. I added 1 gal MA on 25th and the pH was 8.2 on 28th! What is the problem? Possibly the high TA? Or do I need to add MA daily to maintain it?
4) To increase CYA, I got the following item, is it the right one or should I replace it?
Thank you in advance
