I am new to buying a canister filter. In short here is my question.
Since I am tight on funds, can i buy used from ebay/craigslist.
Also, I plan to have a 55 gallon tank. Going by the 5x rule i will need about 275 Gph. Is this true?
Lastly, I can get either:
eheim 2227 professional wet/dry filter.all tubes fixtures included.150.00.
eheim 2217 filter.$80.00
e 2215 eheim filter $70.00
are these good prices and if so which one is good to clean my tank thoroughly. THANKS IN ADVANCE!!!
