safety checks for car and also catchement Q

[terracore]

I used to have a hot tub when I lived in Alaska and adding the chlorine and other chemicals required a lot of testing and attention, and that was a closed system (water only got added to it if I added water to it). Frankly I don't understand the advice from people that say to dump a package of baking soda this and gallon of chlorine that to a catchment tank when you have no idea how much (or if) water is going to be added to the tank the next day, and without any testing to boot. At least with the hot tub, I was only soaking in it, not drinking it. I guess if you aren't drinking your catchment tank water, or using it to brush your teeth, or wash your dishes, or ever shower or bathe in it with an open wound like a tiny scratch, it would be OK.

I will now give it a name: "catchment tank roulette".

p.s. "catchment tank roulette" is now copyrighted and trademarked by me, but I will allow you to use the abbreviation CTR without paying me any royalties.
