Does a sand filter pump use chemicals?

We are exploring options and my husband bought a sand filter pump but we don't see anything about using chemicals?

You need chlorine to keep any pool sanitized regardless of pump / filter type.

So where do I start no directions with anything

Some questions for you:
-- What kind of pool do you have and what is the volume?
-- How big is your pump?
-- Do you have a test kit and if so, what kind?
-- Is the pool already filled?
-- What is the source of your fill water?
-- What all have you added to the pool -- meaning ingredients and not just product names or 'shock.'

Read a lot here on the forum, especially the stickied thread at the top of the subforums. Also, read on our sister website www.poolsolutions.com

bring your stabilzer to 30-40, (buy from walmart) use bleach/liquid chlorine to use to chlorinate (bring it up the amount suggested by ben in his best guess chart), bring you PH to 7.4-7.6 range and you'll be good! I use muriatic acid (PH down) borax (PH up)- (or aerate), liquid chlorine (more cost effective in my area then bleach). and stabilizer from walmart - only put that in once a year.
your pool will be shiny clean!

What is rural water?

Actually, instead of following the advice given by the poster above, you might want to use our simple 'recipe' for starting up a pool.

Go to the section of the forum for Intex type pools. One of the stickied threads at the top gives the recipe. (Until your registration is upgraded, you will have to log out first to be able to see the rest of the forum.)
