Advanced Nutrients PH up & PH down, anybody know the concentration percentage of these two products?

-Botanicare PH up:
29% Potassium Hydroxide

-Botanicare PH down:
29% Phosphoric Acid

-Bluelab PH up:
35% Potassium Hydroxide

-Bluelab PH down:
35% Phosphoric Acid

Advanced Nutrients PH up:
(?%) Pure Concentrate Potassium Hydroxide

Advanced Nutrients PH down:
(?%) Pure Concentrate Phosphoric Acid

Check google for the MSDS for those products.

In terms of potassium hydroxide, you really should just get potassium hydroxide flakes. (i think essential depot has the best deal)

The reason I'm asking is because I just bought the Bluelab PH Controller Connect, and I read in the manual that if the acid or base solution used with the controller is too strong, it can cause damage to hoses and pump. They recommend using their very own brand of PH up & PH down with the controller, but if I can some how dilute the Advanced Nutrients kind that I already have then I can save some money and the hassle of ordering online again and waiting for that crap.

I read somewhere 75-85% for ph down

So did I, but is it official?

ph up 100% ? says its pharma grade.

I'm sure about the phosphoric acid being too strong can very likely damage the device, but what about the 100% potassium hydroxide? Can the potassium hydroxide be as harmful as the acid?

Probably do not want it on your skin a lot or to drink it...

Why not just mix a known amount of potassium hydroxide with water so you know how exactly how concentrated it is?

I have 1 liter of ph up and down, but after I'm done mixing my nutes and even before for that matter, my water is already quite on the acidic side, so I really just need ph up for now. I was thinking about cleaning an empty 2 liter bottle of Pepsi and filling it with the 1 liter of ph up plus 1 liter of water (1:1) and calling it a day, any thoughts?

Well I just stuck the 1 Liter of PH UP in an empty 2 Liter Pepsi and topped it off with 1 Liter of R.O. water (1:1), seems to have done the trick.

AN phosphoric acid is 75%
