Ok - so I checked out the Fluval 404 and the Filstar XP3. Here are my questions:
1. In anyone's opinion is there a better canister filter than either of these? If so, what is the brand and model? If not, which of these two is the better and why?
2. Is a pond filter better in the tank (better = more powerful and filters better) than a canister filter? If so, which brand and model do you recommend?
3. For the two models listed above, how often do I have to replace sponges and gadgets inside? (I was overwhelmed when I saw the list of replacement items for these filters).
I thought narrowing it down would make it simple but I feel more overwhelmed than ever. I am perusing this website to purchase the filter: http://petsolutions.com so if anyone can highly recommend anything for filtering that they sell please let me know. I want to make sure my money is well spent and the filter I get really filters great!
