Good morning Lynn and welcome!
When did you fill the pool? Yes, some very basic items will need to be added. New water has no stabilizer (CYA) in it, so you want to use our
PoolMath tool to add anough for a CYA goal of at least 30 ppm for now (see below). Maybe more later since it's getting hot. Add some liquid chlorine (aka regular bleach) for a day one goal of 3 ppm, then once the stabilizer is in the water, always balance according to the
FC/CYA Levels to prevent cloudiness and algae. Make sure the bleach is regular. Never use Clorox brands and avoid any bleach that say splashless or scented. Finally, for now .... check/adjust pH to ensure it's in the mid-7s. Let the pool store run your first tests, but simpy say thank you and leave. Grab stabilizer from anywhere (i.e. Walmart, Lowe's, HD), and regular bleach from anywhere you wish. You can get the muriatic acid (to lower pH) from the pool store for now if you wish. The pH test is about the only thing I would use from the pool store for now.
Remember, never add bleach and muriatic acid at the same time. Also, store the muriatic acid outside in a plactic container away from pets, children, and anything metal. It will be fine in heat & cold. I use a Rubbermaid container, others might use a placstic trash can.
Once your test kit arrives, add it to your signature and post a full set of resuits. Let us know if you have more questions.
Adding CYA:
To increase CYA via granular stabilizer, place the required amount as calculated by the
Poolmath calculator into a white sock and place in the poolside skimmer basket. For those concerned about suction flow to the pump, suspending the sock near a return jet or from a floating device will also suffice. Best never to allow undissolved granules to rest directly against the pool surface. Squeeze the sock periodically to help it dissipate. Once dissolved, consider your CYA adjusted to that programmed (target) level. CYA test readings should show a rise in 24-48 hours, however some pools may experience a longer delay to fully register. Best to confirm final CYA in about 5-7 days before adding any more stabilizer/conditioner.
