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
