They can also be found in the fish aquarium section of a pet food store. Testing clear liquid is easy and fairly accurate, but it's tougher with runoff that's already got a brownish tint. You can run the liquid through a coffee filter to remove some of the solids and that will clear it up and make it easier to measure with the drops or strips.

Do you know if they go below ph6? My bottle tester is very precise but only go's down to 6, not noo good for trying to hit 5.8..
And luckily for me theres no dirt in my growroom this time, messy ol stuff.. My res is perfectly clear so no filtering needed, but its a good tip for all those dirty fingered growers out there lol..
