I'm looking to buy a new test kit for my water. With so many testing products out there it's hard to choose the right one for your tank. I recently bought a nitrate test becuase my last one ran out. It was horrible, the color patterns go from light pink to dark pink and the range in ppm is not very accurate. ex. one color box would indicate 20 ppm and the next would jump to 50 ppm. So I'm posting this thread to see if anyone can recommend any good test kits out there in the market. I'm trying to stay away from test strips. I'm mainly looking for nitrate,pH,Kh,calcium. I would like test kits for Mg, Fe, I, and Sr. but I've seen them very expensive and not sure if it's needed for my tank. I have variety of corals expect for sps. I add Sr, Mg, Fe, and I to my tank weekly and blindly, because I have no idea all much of these elements are in my tank. I assume once a week is safe enough not to over dose the tank and just enough to keep the corals happy. It's not the best way but it's my only way right now.
