What are you lowering it for? Soil feed? hydro system?Looking for input on lowering water ph in small portions of water 2gal at a time. I found some stuff at the grow store but it’s 5ml to 55gal of water. Does anyone use muriatic acid? Or could I just put a drop of the stuff from the grow shop?
Hi, I use it and put 1 drop into a small 1oz shot glass of water to dilute it. When my ph is at 7.00 but above 7 I just put 1 drop in the gallon test it and it brings my ph down about 1/2 a point to say 6.5 then you can use the diluted shot glass of it to get the ph where you want. I'm in Pro Mix soil/peat and I'm not 100% on the muriatic but its no label shit of some kind of acid I got from the grow shop for about $15 Canadian and it does what I want it to.Looking for input on lowering water ph in small portions of water 2gal at a time.

What kind of citric acid? What product?Citric acid is great for soil.
Even lemon juice will work for soil but I would just grab some ph down that lists ingredients as citric acid such as canna organic ph down.What kind of citric acid? What product?
Ph down is not all the same. Some are made of citric acid, some is sulfuric acid, some is phosphoric acid, rarely some is nitric acid and finally some are a combination of any of these.I prefer pH down...its literally made for this situation and I think its easier than using some sort of acid or base on your own.
Interesting, and I see that you said earlier in the threat different acids work best in different situations. Could you elaborate on this a bit?Ph down is not all the same.

Often they dilute it and mark it up. Such as the one I listed you can go buy bulk citric acid dilute it and slap a label on then sell it for 10x the price. Welcome to marketing
Lemon juice or vinegar works in a pinchWhat kind of citric acid? What product?
and baking powder for up works as wellLemon juice or vinegar works in a pinch
Baking soda (sodium bicarbonate)and baking powder for up works as well
Citric acid is not as aggressive but since it's a weaker acid it doesn't hold ph as long as a stronger acid like phosphoric or sulfuric acid.Interesting, and I see that you said earlier in the threat different acids work best in different situations. Could you elaborate on this a bit?

So citric makes better sense with soil and organic grows.
Nitric can be used to increase nitrogen but it's again weaker than phosphoric or sulfuric but stronger than citric acid.
It depends on your goals which would suit you best but all essentially are used for the same purpose
agree 100% Alkalinity is important to know. You can buy. KH test kit from a pet store or see how much carbonate/bicarbonate is in your local water supply usually from the report.Good to know the hardness or at least the ppm of the source water before adding acid. The ph is not always a good indicator.
I use 8.0 ph well water but it has only 150 ppm mineral content so it easily conforms to the medium ph and needs no adjustment.
Your ph up is potassium bicarbonate dissolved in water.I rely on the grow shop guys to steer me in the right direction with that stuff. I probably pay too much for the stuff but rely on the experts....right?....I have some brand named PH Up but my down is some stuff they mixed up themselves, no label wtfk's what they sold me but it works a drop at a time. They probably told me at the time what it was but I'm 67 add a few pipe fulls , a few months and well my memory is not what she used to be.
Also your GH (general hardness) is different than KH (carbonate hardness) things like calcium, magnesium etc will contribute to your general hardness but not your carbonate hardness. It's the carbonates and bicarbonates that affect carbonate hardness. So adding say calcium nitrate may actually lower your ph a bit while increasing general hardness but adding calcium carbonate will raise your ph and will contribute to both.
Just thought I would add to the confusion.
