    You will want to 50/50 it with distilled water only, verify that is is 0 ppm water first. Been using my bottle for years, even gave away some to a friend. I only make up 1/2 quart at a time and it lasts for ever, comes out to 42 1/2%, it will get warm when you pour the acid in but it cools down. Trying to use it at full strength a few drops at a time will be very jumpy and you will blow your ph down way to far in a hurry and have to start over, and it's dangerous to handle. After I add the masterblend to the 20 gallon res. I usually put in a cap full about 1 Tbs. and it knocks it down just about right. Been doing drain to waste this year and don't even check ph anymore or change water, just refill the top up reservoir dump in my pre mixed into a gallon of ferts, a cap of acid and I'm good for 3 or 4 days. I know people will say it's breaking the rules of hydroponics but it has been working well and so much easier that changing water out every week with the recirculating dutch bucket system I ran in past years.
