At the moment I have a 10 gallon fish tank but it is way to small. I am thinking of buying this new tank: which is 75 gallons. I would like your help and advise about what filter should I get (I will go freshwater with plants) what heater, and if it will be good to add a power had. Another thing is that I read the article about the wired use of power filters, but couldn't understand what and how is it use and if I should have one in freshwater fish tank. (I already have a powerfilter) thank you very much for reading and helping!
