  1. My son got a compact filter for his first fish tank. It’s been very easy, maintenance wise. How often should he replace these? I will tell him about the Finnex PX filter that you mentioned.

  2. Prefer this canister filter over the HOB filter for sure. I like that I can use the Finnex PX – 360 for my 10 gallon tank as well.

  3. Does this filter seem a bit overpriced to you? On amazon the original listing price is $47. Seems kinda pricey for a compact filter.

  4. This one sounds like it wouldn’t be a good fit for me maybe.. I’m scared I’d mess up the hoses or something.. I’m clumsy like that.
