What were the powerheads called? We can't tell you to get them or not if we don't know what they are and there gph haha. Can we have some info on your tank (i.e size, etc.)? Most people like to use Koralia's. They came out with the new "Evolution" series. My dad got the 1050 for his 75g and it blows like a hurricane, lil too much flow. You can still buy the Koralia nano, 1, 2, 3, and 4 for pretty cheap. I bought the K1 off
Amazon for $25 shipped. People also like Ecotech Vortech's. I am going to order one today to be exact haha. But they come in 3 different sizes: mp10, mp20, mp 40w. The mp10 is for 5-55g tanks. Most people say there is no difference between the Mp10 and 20. Except you can upgrade the 20 to a 40w. The w stands for wireless. I haven't ever heard a bad review about them except some people say they are noisy and some people say the are quiet.
As for test kits, you will need to test for: Nitrates, Nitrites, Ammonia, pH, Calcium, Alkalinity, and Magnesium. You will also need a hydrometer or refractometer to test salinity. I use API test kits and they work great. I have heard a lot of people (on different forums) say that they use API for Nitrate, Nitrites, Ammonia, and pH. Then they use Salifert for calcium, alkalinity, and magnesium. I haven't heard any bad reviews about them.
Please don't just listen to me. Most of this is just what I have heard and read, not experienced personally. Maybe someone with more experience on the products will chime in.
Where is this store at? I thought Hoover only had Aquarium Designs that moved.
