I know the sealant dries out after a while, but I've never kept track of how long it takes, until now.
By marking the date I added the sealant on the rim with a correction pen like this...

...I will know how long it's been in there and can top it up after a set time.
This is the first one I've done so far, so I don't know what that set time is yet and it doesn't take in to account any losses through punctures, but it's got to be better than my current guess work system, or getting a puncture half way through a ride, then finding all the sealant has dried up and it won't seal.
I just shake the wheel and listen for a slosh...
No sloshing = add sealant
Sloshing = Happy Days
Why not set a google Calendar reminder to send you an email alert when your sealant is getting on a bit?
I don't actually do this, Clobber's approach seems to work OK for me...
When the Internet of Everything finally arrives the sealant itself will send you an email to tell you its drying out.
We opened a mates tyre on a ride, due to a puncture and found the sloshing was actually just water and the latex had formed into a ball shaped object that was rattling around inside.
Good idea though MTG

good bit of stealth bumming by the guy on the left 😆
I've got a pad in the garage/man cave that I make a note on when I change tyres..
Yes, an email alert would be one way, but it's not as if it's got to be done on a specific date.
If I get the reminder on a busy day, I will probably forget by the next day when I've got more time.
I thought about a spreadsheet as well, or more likely, good old fashioned pen & paper, but then I've got to remember to look at it.
With two MTBs and a cross bike of my own, plus Mrs MTGs MTB and the tandem, I don't want to keep removing 10 wheels just to slosh them about.
This way is easy. All I have to do is glance at the rims before a ride.
I do them all at the same time, then check/top up in 3months time. - written on the calendar. Obviously this all goes to pot when I panic fit mud tyres at some event somewhere. So MTG's technique is a little more precise.
How the hell does water get into a tyre that doesn't let out air?
It's not water getting in - it's the water base of the fluid where the latex has degraded (usually into rubber balls). Common to see this if you've not bothered with a top-up for months and months. There will still be fluid sloshing about, but it's useless.
Punctured myself like this the other night - tiny hole that the ancient latex failed to do anything about, despite pishing out in the usual fashion.
Easiest way to find out is to get a tyre cut in the middle of nowhere in the pouring rain with night closing in. That's how I do it anyway.
My top tip is to just use a tube 😆
I find it easiest to spend months evangelising about tubeless, then endure much piss taking when you puncture due to lack of working sealant. (Repeat every 4-6 months!!)
Every time a thread about tubeless pops up, it seems like more and more of a hassle haha
