Yes & no. A couple of the test might be ok, like ammonia , but past that point I would say no.
The Tetra kits are very time consuming to run and after a very short period of time, you will grow sick of testing. Best to get kits for SW testing.
Thanks, KathyC. How about Nitrite? I'm asking because I've been using this for Koi for couple years, still have a lot of it, and my tanks are 2 and 3 weeks old, so I'm particularly interested in Ammonia and Nitrite at this point.
