Baster to add to my 100 liter res. takes 1-2 full Squirts to change the ph from 6.3 and bring it down to a 5.8

interesting. What does the battery acid do other than add acidity? Never knew there was such a thing as a" box of battery acid". Cool! Thanks
Battery acid from the auto stores is just pure sulfuric acid. Sulfuric acid is used in millions of farms world wide as a pH down:

Thanks private. I guess what i'm asking is why use such a
strong acid? Is there a benefit when vinegar is not only less
expensive and easier to handle? Side note love your Easy Hydro
Private. I use ebb-flow but seeing yours might have to try it out.
The acid is diluted with water to make pH down in this practice. It is much better than vinegar as it lasts a lot longer and works as a buffer much better. Vinegar is also asking for problems with pests as it attracts flies like nobody's business. There are other reasons why vinegar is not good in general and really only recommended as a quick in a pinch around the house fix, and not as a full time pH down.
BTW... most people don't need nearly the amount of down as they do up because nutrients themselves are acidic.
If you don't want to mess with sulfuric acid, I'd just order up some legit pH down and be done with it. Overall if you have an issue with your pH rising you will use more vinegar than down and hence not saving money as it's simply not as effective. Also if you have an constant rising pH then that is the issue that needs addressing rather than continuing to dump more down into it.

I'm about done with my first hydro grow but next time around to save on money i'm going to buy the 85% phosphoric acid and dilute it with distilled water (makes gallons of ph down)... something the hydro companies don't tell you but they are making a killing off of it!

don't. I like the phosphoric acid approach seems much more practical.
I'm just the kind of fella that would rather do it for myself than buy pre-mixed.
I still buy straight anti-freeze and mix it myself.
Skiddy6 where do you get your phosphoric acid ?
Many thanks !!

950 ml Bottle of Phosphoric Acid, Food Grade 85% Concentration: Amazon.com: Industrial & Scientific
the main thing i would focus on is that is it food grade unless that doesn't matter but like i said a little more research i could tell ya a little later
dudadiesel seems popular and 85% but there was another guy that was brewing mash for alcohol and picked up some 75% up at the local brew store
looks like duda diesel mainly and you can find that online on amazon or ebay etc...then dilute it with distilled water....13 bucks on ebay for a whole Liter of 85% but yeah try to find duda diesel for cheap
