Sometimes those thirsty notifications don’t line up with when you really do need a top off, and sometimes they do. Sometimes I won’t get one for a long time and sometimes I’ll get them close together and my res will be full. That’s one notification that I really just think is a reminder that goes off randomly to remind you hey, don’t forget to top off every now and then. That’s my take on it based on the way they come to me anyway.
And if she’s drunk a lot, I say why not? If you need to add a couple liters or a gallon, throw in a few more ml of hydroguard too. If you just need to add a cup of water, I wouldn’t worry about it. That’s just my opinion though.
