Red Sea Oxygen Mini Land Test Kit

[fantails]

I was thinking of buying this Red Sea Oxygen Mini Lab to test my disolved oxygen. Does any one know if this test kit is any good?? I do not want to waste my money if not. Thanks

Your fish are the best test for low oxygen.

I've got DO meters at work and have never even needed them...

The fish tell you by their behavior.

Save your money.
