    Help with ID on Muriatic Acid

    We could only find one source of muriatic acid last year, and this year's searches prove to be just as useless. Home Depot sells http://www.homedepot.com/webapp/wcs/sto ... reNum=4014

    That's what I have on hand. I have checked the MSDS and the only indication to concentration says < 25% Hydrochloric Acid. see http://www.homedepot.com/catalog/pdfIma ... 30f5c6.pdf

    This percentage is not on the pool calculator, so we've been doing some guessing and H has done the math for me but it doesn't seem to be coming out as accurate as it should. It's close, but we usually just miss the mark when we use it.

    Can I get some help with this product? Where can we buy the correct product, locally? Pool stores don't seem to carry it (at least in online catalogs). I just opened a bottle of the product referenced above, I'd like to use that up first and then find a better source for something I can use with the pool calculator.

    Thanks!

    Don't waste time and energy looking for a better value on test kits, the TF100 is the best deal around. I did the looking and spent the extra money, but you don't have to make the same mistake. Just go here: TFTestkits. I use Pool Calculator for min/max, and shocking chlorine levels.

    Re: Help with ID on Muriatic Acid

    Are there any other hardware stores in your area? If not you may need to switch to dry acid from the pool store.

    Re: Help with ID on Muriatic Acid

    If there is a Lowes near you they carry 31% muratic acid. At least around here almost every pool store also has it.

    Re: Help with ID on Muriatic Acid

    True, this is a large city... I probably should have investigated some of the smaller hardware stores. Although the two bottles were presented to me one evening upon arrival of the H so I accepted them like a good girl :~}

    Re: Help with ID on Muriatic Acid

    This is what the Lowes website says they carry... which is the same as Home Depot. http://www.lowes.com/pd_58558-78-GKGM75 ... &langId=-1

    I try to stay out of blowes... it's further away than HD and it kinda blowes IMO... as such, I haven't actually checked the store shelf or called to inquire. Could it be a location issue? Only green acid available here? (anyone seen Portlandia, the tv show? A bit extreme but not so far off as to be able to tell people it's fiction...)

    We buy it at Ace Hardware, but have to ask for it. They do not keep the gallons of the 31% out on the floor. They do keep the smaller bottles of the "green" stuff out.

    Re: Help with ID on Muriatic Acid

    Again... A big TY for the research and link... but NO GO at any local stores. HAS to be a regional issue. Weird huh?

    Re: Help with ID on Muriatic Acid

    In my lowe's they don't carry it in the pool section. It's in the paint section with all the solvents and the like. Also online, lowe's says my stores don't have it, but I know that is where I got mine. It might be worth a phone call to the stores themselves and see if it is there.

    Re: Help with ID on Muriatic Acid

    Both Home Depot and Lowes carry 31% over here, but they are in brown boxes. This is what I have been buying:

    http://www.homedepot.com/h_d1/N-5yc1...atalogId=10053

    I find it in the pool section. Also Lowes has it in the box as well, 2x 1 gallon jugs.

    Re: Help with ID on Muriatic Acid

    Use the 25% MA and don't waste time looking for 31.45% or 28.3% etc. Use the 28.3% setting in the Pool Calculator and add 10% more. If the PC calls for 10 oz., add 11 0z. Eazy-peezy!

    For the accuracy of our pool water chemistry, ball park is OK. It's like, "measure it with a micrometer, mark it with a grease pencil, and cut it with an axe."

    Good luck!

    Re: Help with ID on Muriatic Acid

    I doubt that any online search will find muriatic acid, since shipping it would be a nightmare.

    Just phone the local stores, both Home depot and Lowes will have it.

    Online searches have that limit, they only show what they will ship, not what the store has stocked.
