Aside from it being powdered (diluting is necessary) and pretty concentrated, is it ok for dwc? These are the active ingredients: sulfuric acid and monosodium 95%.
Is PH down for swimming pools ok for hydro growing?

PH down is extremely cheap and made to be safe for hydroponics. GH makes a good PH down.
Wait... Did you say swimming pool?

Excellent question and sorry I don't have a suitable answer because I just don't know. If a pro-grower answers with "no", then I'll be asking myself, "would I swim in a pool that has a pH down in it that kills plants"?

I'm just a fan of stuff made specifically for hydroponics that's all. I prefer the GH PH down. I might not save a buck but at least I feel I have the right stuff for the job.

Will it work? Yep it sure will ph down is ph down as ph up is ph up. You can even use dolomite lime or lime juice and other things as natural stuff in your soil so you don't need to adjust.
It's just not marketed towards plants is all. Ph up/down isn't really that expensive though

Well, most water out of the tap is 7+. That's all I use for PH UP. Down is what you really need, especially if you're a hydro grower.

With my nutes(dyna grow) I don't have to use either
My water is from a well and I just add the right amount of nutes and it puts me in the perfect range whether I'm in soil or hydro

Yeah that stuff is pretty tight. I'm still doing a lot of old school stuff so I'll probably always be chasing PH numbers around. Plus I've ran the same 3 part series for.... ever basically, so I'm pretty hesitant to try anything new to be honest.

Yea I love it. Makes it really simple. I only use my ph pen once in awhile just to make sure things are still good from my well.
If something isn't broken don't try to fix it. Just improve it

Yup, the only thing I've needed to add is GH calimagic and gro-tek instagreen. It's not needed, but it helps my aggressive vegging.Yea I love it. Makes it really simple. I only use my ph pen once in awhile just to make sure things are still good from my well.

Thanks to all. I was thinking of going with dyna grow or ph perfect next time around but Om to far in this time around (wk 7 flowering).
Active Ingredient- Sulfuric Acid, Monosodium Salt 91.5-94.7%
Are these the se for liquid ph down?

Oy. I'm not sure I'd use anything in my hydro grow that you use in a pool. It seems like those chemicals are too toxic for something you're ingesting.
Interesting idea though.

I dont think I've ever used any of my ph up. The bottle has just sit there while I've gone through bottle upon bottle of ph down.

Yep. I just buy PH down buy the gallon now. You use enough of it in hydro setups.

GH ph Down is made from phosphoric acid. I think the pool stuff (and a common DIY recipe) use sulfuric acid. What's the difference? I dunno - not a chemist.

Hey man. Ive used it. Works fine. But some of that pool stuff wont bring your ph down below 6.5-6.9. Every brand is different. Just make sure it will bring the water to the ph that you want. Just my 2.......
