thanks for the imput, upon reading up on them intensively on the internet it seems as if some people love them and others think they are a waste of money, as i have never used one i am not sure what side of the fence i sit on, but when it comes to quality it seems like the one that i have is on the higher end of them, putting out 500 gph which on my 75 gallon tank is a turnover rate of 6.6 times an hour but i would place it before the skimmer on my sump so im guessing that i would want the rate would be less than that. that being said, knowing that a majority of my water would be going through it do you think that it would be worth keeping?
before i make my jump to saltwater there is many more things i need to get, and right now i am leaning towards seeing how much i can get selling the uv filter and putting that money into other things that i need.
how much do you think i could get for this filter? she said that it had been used about 5 months on and off and it sells new for around 170.
