Welcome!
The best thing we can do is educate you about pool care. It seems mysterious and difficult, but it's actually really simple and easy in 99.99% of all pools.

Pool stores and pool services are lousy sources of information because if you KNEW how easy it was, you wouldn't need them, certainly not the pool service. So they keep you ignorant and scared and remove your money from your wallet.

Pool chemistry mainly comes down to three things:

1) Chlorine levels for sanitation. Your salt-water generator makes chlorine from salt, but it's still chlorine just like bleach.
2) pH: this is how acid or alkaline your pool is. Neutral is best, but for difficult-to-explain reasons, "neutral" isn't 7, it's actuallly 7.2, to 7.8. Too acid and the water irritates and can damage your pool. Too alkaline and it can irritate and inhibit chlorine doing its job.
3) Stabilizer. This is like sunscreen for chlorine, protecting it from UV rays. But it slows chlorine down, so you need a higher basic level of it. With your SWCG, you should keep stabilizer in the 70-90 range (depending on what the manufacturer calls for) and chlorine at NO LESS than 5% of the stabilizer level, at all times.

Go to our sister site, poolsolutions.com and and spend an hour reading the tips there. You'll find it's all much easier than you think. There's no reason you cannot have a crystal clear pool your neighbors and friends envy for minimal effort and cost. It's what we here all do.
