    Purchased 40 pounds to add to the 15,000 g pool. Used 36 pounds for 50 ppm (2.4/2.5 pounds for 10,000 gallons) is what they recommend I saw videos about adding boric acid to hold off algae and help hold the ph steady . Videos mentioned another company to get boric acid from but after reading some of their reviews about how they treat their customers I searched for a different vendor. First time dealing with boric acid but seems like high quality. Dissolved very easily. I brushed it once twice and it disappeared. Very happy with the product and the great customer service!

    Effective Roach Killer

    Posted by Ken on 9th Feb 2022

    My brother had a visibly serious cockroach infestation throughout his whole place. I researched solutions & came across boric acid. I sprinkled some behind/between the fridge, stove/oven, washer/dryer, & in bathroom cabinet. There was a noticeable decrease within 2 days & they were all gone by day 7. HIGHLY RECOMMEND!

    Great price for 25kg bags

    Posted by TJR on 24th Jun 2021

    Bulk Apothecary has the best delivered price I've found for large quantities of boric acid. We use about 40lb per year for our swimming pool and have bought from them for the past several years.
    The product is well packaged and normally delivered in a few days. One thing to consider: The past few years, it's been powdered boric acid, looking like powdered sugar. This year it was granular, about like kosher salt. Either one works fine for my application, but if you require a specific form for your application you may want to ask before buying.

    Boric Acid water quality research

    Posted by Owen Davis - Oregon Fish and Wildlife on 11th Mar 2018

    Bought this product for water quality testing for nitrates on my fishery water quality study. Has performed flawlessly and pure. Tested in lab for potential phosphate interference and found none. Would definitely buy again

    As expected thank you

    Posted by Unknown on 25th Jun 2017

    As others have mentioned this is the best price online and most pharmacies don't even know what you're talking about when you ask for boric acid so this is a great resource! Thanks again.
