You don't want to store it in a jar full of the stuff as it precipitates out into salts that will crust your jar as it evaporates. I have a larger cap for the electrode that I fill, but it has to be replaced monthly. Even then, the electrode craps out after 2 years. (I use mine for winemaking, not gardening).
There is no reason to ph down 3 times a day. Your meter is bonkers. That's a technical term that means your meter is bonkers. Ph meters are very delicate and should be stored in this. If you store it correctly you shouldn't have to calibrate often, but if you do not, you will have to calibrate ever time or you will get wild readings.
If you follow a well designed feeding schedule you shouldn't need a ppm/ec. Most nute manufactures have well balanced feed schedules available online. If you are trying to hyper feed or make your own custom additions then you will need a ppm/EC meter or you will run the risk of lockout.

But plenty of people used distilled or RO water just fine. I don't know if I'd use tap water, just because it could be fine or it could be terrible.Edit: See below.
