I am using API's test kit. Should I get a different one? I only have 3 small fish. A Tailspot Blenny, Percula Clown (small) and a Babrbershop Goby paired with a Pistol Shrimp. I also have a Cleaner Shrimp and an Emerald Crab. 2 Scarlett hermits, 5 very small blue hermits and a bunch of different snails. There is thirty pounds of live rock and a nice thick live sand bed. Here is a picture. As for my filter, I have a Pengium 170 bio wheel (w/o bio-wheel) and a Aqua C Ramora Nano protein skimmer.
