Unless your water sourse has an incoinsistent ph, usually we only need either the phUp, or the phDown. Rarely both.

Watch for metals and salt build-up when using Baking soda. I used to keep corals (saltwater tank) and remember reading that there's metals and such in the impure forms of BS.

The link below is from one of the sites I used to frequent, and is all you ever wanted to know about buffering water ph with BS. But it does open-up a snakes nest when trying to figure-out carbonate hardness versus general hardness...and other little technical facts like that. But it's doubtfull that you'll want to keep and maintain a 8.2 to 8.4 ph, so you won't be pushing the limits nearly as hard as saltwater reefers do. Was great for me...my tapwater comes out at 7.9 to 8.0 ph. Very little adjustment necessary. :thumbsup:

Rusty Trichome Reviewed by Rusty Trichome on . adjusting ph levels Well I read on a website that a good home remedy for lowering/raising your ph levels is either vinegar or baking soda so I added a tiny bit to my plants water, tested it, and my ph was back to normal. I was wondering even though baking soda is good for adjusting the ph, is it good for the plants and how often should I use it? Thanks! Rating: 5
