Citric acid good / bad

so is citric acid ok to bring PH down my water is near 8 from tap ?
up date i had ordered PH down on Amazon i was going to cancel it but to late. so i did a test i have a color q 11 pro test kit for pools and a taylor k6000 liquid drops (phenol red) my taylor says 7.8 /8 its subjective to color bright red is 8.2 any orange ish is 7.4 this kit reads high PH i doesnt go in to the low to acids. the color q says 7,2 ??? the blue labs pen says 7.9/8.1 so im sure i need to take the high and throw the color q away

Citric acid will work. I’ve used lemon juice, and vinegar. There is another thread about this here How to read ppm’s?
Specifically, the part about homemade vs. premade pH buffers.


I use distilled vinegar without any problems it works just fine I’ve always used it there’s some interesting stuff out there that can be used instead of using ph up/ph down

Thanks a lot for you guys help

I use fresh lemon juice, (because it’s free). No noticeable issues yet.

Do you own citrus trees, or borrowing it from work?

Leftovers from work at the end of the week. Honestly, it doesn’t take a lot of lemon juice to bring things into check. 2-3 lemons for 3-4 plants/ week.

All I know is that citric acid can be nasty stuff. Be careful

I use it myself. It’s rare I need it, though. I never have to get juice or lemons, since my wife loves lemon, on everything. We always have lemons. I’m going to grow a dwarf tree when we have the space.

I’ve tried growing citrus plants here, they never amount to much. They veg and veg but never flower. The climate here just doesn’t support it.
I’ve got 2 cherimoya trees in containers that I’ve kept going for 8-9 years. I’d love them to flower, but I’m not putting them in my tent. Real estate is valuable.

Which neck of the woods is “here” that they don’t do well?

New England. Between ny and nh, but not Maine or mass. :innocent:

Ah. Yeah, I would think they’d be tough to grow up that way. Here in the desert, I bet they’ll do great. They do in Phoenix, I know.
