PH up? Sodium Carbonate?

Can i use sodium carbonate for ph up without killing my plants?

it won't kill them, but some say it may harm them or the medium in some ways.

Washing soda, sodium carbonate, is an alkaline with a pH of 11, and while it doesn't give off harmful fumes, you do need to wear gloves. It is found in the laundry section of most supermarkets. Arm & Hammer is one brand; Shop and Save has a generic house brand. It is also known as Soda Ash. You can also buy it from swimming pool supply stores; a popular brand is pH up. This is not the same thing as baking soda, also known as sodium bicarbonate. Though similar, sodium carbonate is a much stronger base. Moderation in all things! Adjust your water to determine how much you need for your reaction. My city water 1 aspirin to a gallon lowers ph .6.Experiment so you do not burn your plants!

yeah. this is just a sub until i can get a hold of some real ph up. Its called PH up but its for pool water. just wondering how long i can use it untill i have to get the real stuff
