I bought those exact test strips and used them at first. I realized, however, that they don't last long and they're $13 per box. After I'd bought two sets, I realized I could have practically bought the API master test kit, so I finally sprung for it, as it lasts way longer!
I found that the test strips were in the right ball park when compared to my master test kit. The nitrite and nitrate readings were accurate. The pH reading was off by about a point. I thought my tank was at 6.8, it's really at 7.6 or so.
I'd say they're okay for a general reading, but ammonia is what you really need to be concerned with, since you probably can't cycle tanks that small effectively. They sell the individual API ammonia tester (http://www.marinedepot.com/ps_viewit...content=AP3131
) and it does 130 tests. You may be better off just getting that for now!
