I finally decided to put my 29 gallon fish tank back together for my son who showed interest in fish after visiting a local fish store. Not wanting to make a big investment at the time I just set everything up like I had it 15 yrs ago which includes an amiracle 50 wet dry filter and a rio 2500 pump. The LFS talked me into buying 13lbs. of live rock to help cycling. Its been 5 weeks and my nitrates are finally at 0. After speaking with different fish stores half want me to get rid of my wet/dry for a hang on back filter and add a protein skimmer. I am willing to purchase a new filter if it wil ensure better water quality and healthier fish. I have gotten suggestions to use aquatop PSE1 or a aqueon 30. Please help confirm the LFS suggestions or if the current setup is adequate for good filtration. Any help is appreciated. Thank you.
