I went to leslies to test my water and the results included a value of 27 for calcium hardness. I never tested for this before because I have a vinyl liner and thought it was not relevant for my pool. Could this have a negative effect on my heater. What about my salt generator? What about the steps, aren't they fiberglass? Thanks

Vinyl liners only need CH if you have a gas heater...which you do. You want CH of about 200.
Are you using poolmath? Get it here...link-->PoolMath
Configure your pool and put YOUR test results in. Turn on TRACK TEMP and TRACK CSI.
With a SWCG, you want to run your CSI between -.3 and-0. My guess is that your CSI is much lower.
Why are you pool store testing when you have a k-2006c?
Sincerely,

Stay away from Leslies "free" testing.
Use your K-2006C and K-1766 test kits.

I have had a real problem with my heater and am looking at repair or replace options. (This link is the original discussion My pool heater kinda blew up so I am seriously considering a replacement )
Today I found an apparent long term leak from the area by the heat exchanger and I was talking with a repair guy on the phone. He wanted to know what the ch value was and suggested the big L for a test. Anyway I will do my own today and double check. I have a bag of calcium chloride in the garage, whats the best way to add it to the pool? I would imagine mix it in a bucket and then add to the pool. I will look into the csi test also.
Calcium products should be spread across the surface of the deep end of the pool. Do not mix calcium in a small bucket of water. Calcium is exothermic and will generate heat when mixed with water to where it can cause burns or fires.

Calcium doesn't actually matter for gas heaters. It only matters during the warranty period because the manufacturers are using recommendations for steam boilers, which gas heaters aren't.
But low CH can void the warranty so we recommend following it as it does no harm.

I'll echo that about CH and heaters. Not that a single use case proves anything. My city softens the water, so it was always a battle to get the CH up to traditional recommendations. Hard to find affordable Calcium Chloride, and I needed a lot. So most years, I ran very low. Breath of fresh air to learn here that it was something I didn't need to worry about. As far as the Raypak heater - I thought this would be the year, but it still fired right up with no leaks. 22 years and counting......
For CH and CYA I like puritech $50 for the 25lb bags on Amazon.
13lbs of Baking soda (a lifetime supply) is under $10 at Bjs / Sam's/ Costco
Muriatic acid (full strenghth) is $9.99 at Ace Hardware. But you'll rarely need it once everything is in range.
Walmart has 10% liquid chlorine for $5.67, local pool stores may have a better deal for 12.5%. Bjs had a few pallets in the spring but it was sold out quick. In the upper left menu of poolmath is a bleach calculator to show you the better deals of % / $.
20 mule Borax is $6ish for 4 lbs in any laundry aisle and again it won't be needed often.
I Google salt before I go at Walmart HD and Lowes. They flip flop whether the pool salt or water softener salt is the $8 one. ($11 for the other). No chlorox salt ever. Always make sure the bag you like says 100%, pure, and/or additive free.

Should you not be concerned that the hot Calcium Chloride will damaging the liner or plaster? I've always done it in a bucket, just kept the bucket in the water to keep it from melting.Calcium products should be spread across the surface of the deep end of the pool.

Welcome to TFP!!
Nope, no concern. The amount of surrounding water is so large, it can't damage the liner, is spread across the surface. 95% will dissolve before it hits the bottom. The rest is gone in 1 or 2 brush strokes.
