I just went to PetSmart here are all the things I think I need for the basic tank set up..Tank Protein Skimmer Filter etc. Can you please tell me if I'm missing something (This obviously does not include the actual things for inside the tank Live Rock Sand Etc.) 28G tank (I'm gonna get a dwarf bimac don't worry) 79.99 Power Filter (I believe made by penguin) 74.99 Protein Skimmer (Didn't have much of a selection anything I should know about this..Does it matter who makes it any recommendations etc.) Water Pump (Does it matter what size it is where it is placed in the tank etc?)39.99 Thermometer Heater (Questionable) Nitrone Testers Bubble Walls/Airline Tubing/Air Pump Hosing to take water out of tank (Called Clean And Fill) Ummm what am I forgetting? Also is it better to have a filter that's under the sand? Or should I get a filter under the sand and on the side?What kind of filter is best? Any information you guys can give me would be GREATLY appreciated!!
