I agree,,,GH is good,,,trusted for years.I personally use General Hydroponics brand. Plants have no issue with it at all. I have very hard water, and use a lot of it, no problem.
GH PH DOWN is made from phosphoric acid, which makes your reservoir pump and hoses slimy, especially during flowering. When the phosphoric acid hits the P saturated solution, a plume of phosphorus hits the water and the solution cant hold it all, some of it changes form to a solid and it becomes slime that sticks to everything it touches. I use sulfuric acid and I get no slime at all, all I have to do is rinse out my system once a week, almost no scrubbing at all.I currently run Mad Farmer up and down with the whole line of H&G aqua flakes.

You can get sulfuric acid at any auto parts store, just ask for battery acid. Cost is anywhere from $3.99 - $5.99 per liter, very cheap. You have to ask for it, they keep it behind the counter. Wear rubber gloves and goggles while handling it. For weaker strength, use 1/3 of a cup per gallon. For normal strength use about a half cup per gallon. Make sure you use RO water or distilled water. You dont want the chlorine from your tap water interacting with the sulfuric acid. A $3.99 container of battery acid will make about 8 or 10 gallons of PH Down.
For PH UP use 100% pure lye. One level tablespoon makes a gallon, which lasts years. Lifetime supply for under 5$.
Read the ingredients on the lye to make sure it is PURE sodium hydroxide or pure Lye in crystal form. To make the PH UP, fill a gallon container 3/4 with RO or distilled water and drop one tablespoon of lye crystals in, then top off with the rest of the water. Wear rubber gloves and goggles. I will never ever have to pay 25$ per gallon for UP or DOWN again!!!
I have been using sulfuric acid for PH down for my last two grows. After spending $10 on a small bottle of fish PH down I see it contained sulfuric acid. Didn't take much for me to figure out the cheap way was the auto shop....

i can't tell you what's the best, but i can tell you that i have used general hydroponics for the last 3 years without a problem.I currently run Mad Farmer up and down with the whole line of H&G aqua flakes.

No issues at all. Battery acid is pure sulfuric acid mixed with a little pure water. Just be very careful handling it. It is best to use it up all at once and make several gallons then toss the container that it came in.man battery acid! holy smokes. you dont have any issues with it? im so down to try.
Well, people use it in their fresh and salt water fish tanks. In salt water tanks the coral, fish, and other animals are NOT CHEAP.man battery acid! holy smokes. you dont have any issues with it? im so down to try.
This is what I use also, but its best not to add any PH. After I mix everything and PH is say 4.5 close to my target 5.8, I will add some more protekt silica and PH with that, but if I have to add too much( more than 2.5ml/gal) silica I will use the mad farmers PH(great product)I currently run Mad Farmer up and down with the whole line of H&G aqua flakes.

Just make sure it is pure lye or pure sodium hydroxide
Hope this helps.
wow! thanks for the new found knowledge i jus gained.No issues at all. Battery acid is pure sulfuric acid mixed with a little pure water. Just be very careful handling it. It is best to use it up all at once and make several gallons then toss the container that it came in.
Vinegar also works well, but I have always found that it wears off quick.
With the lye make sure that Lye is the only ingredient (100% lye, 99.9% lye, or 100% sodium hydroxide) and that it is in crystal form.
