Good to hear from you! Swim season is approaching. Yay! The tests will get easier, and fill water can be a bit tough to test like Kim said. You might want to take a fill-water sample to a pool store that tests for metals also.
For the PH test I found that holding a white, plastic plate behind the tube and pulling the plate back and forth until I have a close match. I do this under a very bright light.
FC-you were testing your fill water? Chances are there is little to no FC so your test was correct.
I am going to post a link to videos of the tests. I hope they help. Let us know it this does not help and I have another idea if needed.

Let me know how it goes this time.

Well water will have little to no FC in it so you are fine! If you want to make sure your powder is working you can dip a tooth pick in some bleach then put it in a cup of water and swirl around. I bet you see some pink then! LOL

I wouldn't buy any more chlorine right now. The strength will degrade over time. I still recommend going to a pool store or Culligans or something to test for metals.
I would also use the same service to test your current POOL water for metals once you open. Since you had that dreaded Pool Frog, (which I hope is now non-functional), that may have introduced additional metals too.
I keep the Frog connected and use it when I go out of town. It mostly contains silver not copper so in occasional uses it should not stain your hair or pool.
Defgufman,
I think we have to be clear here that this is NOT an endorsed method of pool care by TFPC standards. While we all agree that you and I and others are free to add whatever we want to our pools, using metal sources of any kind are both unnecessary and possibly detrimental to pools.
Unless something has changed in the design, the Pool Frog (for pools) is a combination of silver and copper metals (for spas, they use silver and zinc). Even if the cartridge is mostly silver, the problem with this is the Frog is adding silver ions for no good reason and there is no way to know what concentration of metal ions are in the pool water or how much is being added. In a residential, low bather-load pool setting, chlorine is much more effective for killing algae and bacteria. Depending on the bacteria type, chlorine has CT kill times on the order of 1-2minutes while silver ions take as long as 10-20mins. Even when the two are considered in combination, there's no point in adding silver as pools don't generally have high bacteria loads and, very rarely, only have bacteria that chlorine has a hard time killing. Also, we do know for a fact that metal ions, at a high enough concentration, will precipitate out of pool water as stains. Silver stains, in particular, are exceedingly difficult to remove as they do not respond to any of the standard metal removal techniques, eg, ascorbic acid. Vinyl lined pools are less susceptible to metal stains but we only have very limited data with regard to silver stains and we know that both iron and copper can stain vinyl if the conditions are right.
My point in writing this post is not to attack your methods (you are free to care for your pool however you see fit) but to make sure that the OP knows that the use of metal-based disinfectants are not supported by the facts as we know them and TFP does not condone their use under any circumstance.

But yea, I'd remove the frog, or at least the minerals in the frog if possible. I busted open the Nature2 my PB installed and took out all the metal balls. Water just flows through it. It's doubly pointless when I have a SWG.
Husband said yes it is the same. Thanks hubby!
