Could some one please tell me what would be the best power filter for a 55g fw tank. Ive looked at the web sites and seen about +60 different types. Whats the difference between wet/dry and just wet? Do I need that really? Am I really going to need a phosphate killer and a calcium whosawhatsis. I guess just give it to me straight what do I relally need I dont want 100 gadgets that will collect dust under the tank that I may use once and never again. What water test kit preferably inexpensive. What fitler, one that doesnt set me back for replacments too bad. I understand that more is better so I should expect 5x the volume for gph or more right? Are biowheels really the way to go Im not really stupid just really confused. Ive looked at the sites for Marine Land, Aquaclear, Tetra, Millenium as well as others. Oh yeah I was kinda hoping it would be a simple one to use too. Something that doesnt take a degree in engineering to troubleshoot and maintain.
