Test kit poll
I am getting hard time to figure out what test kits to use because i have been used couple test kits and their result are varies from branch to branch. For example. I used IO to test my ph and it says 8.2 but my API test says it is 7.8, same for nitrate, IO says it is < 10 but API says it is 20
It is a huge differences, I know that these test kits are not very accurate but what is the best test kits our there for the money? Please vote and explain
