stuff used to lower ph in aquariums
To Ron I know you are a hydro man but i was wondering if you could answer a soil question for me. Is sodium biphosphate ok to lower the ph in water before I water my plants in soil. This is the same stuff used to lower ph in aquariums. I called my local brew and grow and the guy said if I was using this in dirt it would be ok. But the sodium part Makes me worry about what's in it. THANK YOU FOR YOUR TIME

You can use just about anything with soil because unlike hydroponics soil has a buffer from the chemical reaction to the roots. You have more time to correct your problem because of this buffer. With hydroponics you have to fix imbalances right away because the nutrients go strait to the plant roots.
