Understand that no test kit is perfect, and that some people have had problems with a few of API's products, but I've been pretty happy with the Red Sea "Marine Care Multi Test Kit". It has all the basic tests that you need for starting a tank assuming that you'll keep up with water changes. It doesn't have a test for phosphates, though, and you might want to look into that, given the tank's algae problems.Perfect. Do you have a suggestion on what test kit?
