Ok, this is soooo strange. I've just rinsed out my 2 drop checkers. Filled them both back up again, with exactly the same solutions, one is blue and the other is a diamond green colour!!! So strange! Both solutions are exactly the same! I've retried it loads of times - the small drop checker is always green and the larger one is blue! However, if I mix it in the big drop checker and then pour it in the little one, it stay blue. What's going on?!

Move them both around the tank - it could be down to poor circulation. It could also be one DC has more of an air pocket so it will react different and in some cases change colour quicker. DC's are great for roughly estimating the co2 levels, but the best method is visually. If the fish aren't gasping, crank it up a bit :D
