What brands of PH pens are you's using?

[Kloud9]

Honestly the calibration set is overpriced you only get enough sachets of solution to do two tests and the cleaner is just dishwashing liquid and a soft toothbrush, you get a couple small plastic containers to calibrate in as well, woohoo

A lot better value buying a bottle each of 4 and 10 calibration and one of storage solution shouldn't be more than 8 or 9 bucks each and will last years instead of two months (bluelab pens want calibration every 30 days).

And you can go for months without calibration also. Solid device.

Yes I think so..

You sure can I've let mine go a week or two without the tick and it doesn't seem to read any different.

Ahh. Ok. Can you use any brand calibration fluid, as long as it is 4 and 7?

Yep 4 and 7, or 4 and 10, pretty sure you can use either

Edit yeah this is from bluelab site

Yeah bottle of 4ph and 7ph isn't for calibration?

I think it is

My problem is i can't seem 2 throw away ph solution after using once
The bottles yell at me "don't be a waste breed, tip that shit back in"
Don't know if it stuffs up rest of solution or not
