lol XD no worries, I told you I don't mind the questions!!! and yep, I'll go find that in a bit. For now, work is over so I'll be driving home and I can't have my laptop out and drive at the same time XD hahaha
Oh no, you have to keep dosing each day if it falls below 2ppm (or 4ppm) that's why you need to test daily and if it's down at 1ppm, you redose to make it up to 2ppm so it stays there. That's probably why you don't have nitrites yet, you're not giving them food each day!
And nope, never volunteered at a shelter! We have a few around here but they're really tiny and don't do much with volunteers unfortunately.
