I am about to purchase some sand from a website called trademe, where some one is selling two different kinds of sand. the first has been stated to have a ph leve of 7.5. what does this mean is it good? it comes already cleaned and looks like beach sand except it is salt free. the second kind has a ph level of 7.2 and says it is natural looking with small micro stones in it that are natural. is this good? im at a complete loss for which sand to get and dont want to buy some from a building place as i dont know what might be in it.
any help is appreciated
