I have been thinking about picking up a new filter for my 50 gallon tank. I have been looking at the 360 c-series from marineland but I have just recieved an offer from a friend who wants to sell me his newer trickle filter complete with bio balls, pump, sponges and overflow box off of his 75 gallon for alot cheaper than the marineland will cost me. I have a trickle on my 60 gallon with a Magnum HOT and it seems to do a great job but Im not experienced with the newer canisters. Cost is really not my concern but a few bucks saved is never a bad thing these days. But, if the canister is better I would also like to take advantage of that. Which one of these filters provides better filtration for freshwater? They will not be the only filter running on this tank, I also have 2 penguin hob 200 w/ bio wheels that will stay. Any opinions and why? Thanks in advance!
