Nice to get a rough estimate of CO2 levels, the PH check could be pita but it works great. You can try a blackout solution, but for now it's not necessary. If there is algae on it, simply remove the suction cup (you can leave it in warm water to soften it) and then soak the jar a little in a bleach solution, rinse and refill.
