Hello everyone!
Alright, so I have the 10 gallon tank, the decor to go in it, the gravel pump and the gravel! However, before I can put Bo or plants or any tank mates in, I need a filter to go with it!
Thanks to BettaisBetter and about five trips to different pet stores, I found two filters with really good reviews that fit my budget!

However, I would like to get your opinion on the matter~
The two filters are:
The Tetra Whisper 10i and the AquaClear 20 Power Filter!
So far, I'm leaning towards the Tetra Whisper because it's cheaper ($11 at PetSmart) compared to the AquaClear 20 ($25 at PetCo; I couldn't find it at any PetSmart near my house!)
Also, the Tetra Whisper seems to only need one component of the filter changed over time (the Bio Bag)... however, every pet store I've talked to says that the AquaClear 20 would be the better choice, especially since I intend to get Bo a compatible few tank mates.
AGH! Please lend me your years of fish knowledge and expertise~ I would greatly appreciate it!
Thank you for your time and have a great day!
Sincerely,
Caii and Bo
P.S.- Bo's happy, healthy, and saying hi! ^^
