Doesn't Add Up (or I'm Being Dumb)

    The box for the Fluval 306 Canister Filter says:

    300 Litres / 70 US Gallons

     

    But 70 US Gallons is 265 Litres? What an I missing?

    ( P.S. 70 Imperial Gallons is 318 Litres - so that doesn't help)

    300 liters is 79.26 US gallons.
    265 liters is 70.81 US gallons.

    Typo? Plus it's talking about approximate aquarium size, not flow rate.
     




  3. Nick72Valued MemberMember

    Yes that's what I'm saying.

    So a company that specialises in engineering aquarium products can't convert Gallons to Litres?

    And in what world is 265 approximately 300?

    264.979 is approximately 265, which is why I'm saying 265. It's a long way from being 300.

    The flow rate says 1150 L/H - 303 G/H, which Does add up.
    Not sure on the other numbers - my guess is that they are saying what approximate size aquarium it's suitable for... most people aren't buying a 79.26 gallon aquarium :D lol

    Yes I get your point, but people don't buy filters that are rated to exactly match their tank volume. A 70 gallon filter is probably appropriate for tanks of 45-70 gallons.

    So why not say 70 US Gallons / 265 Litres
     
  6. CichlidudeWell Known MemberMember

    Well not sure. Do they make a 265 liter or a 300 liter aquarium? Which do most folks buy?
     
  7. AlgonquinWell Known MemberMember

    good point... curious to see what Fluval would say on this... :)
     
  8. GalathielWell Known MemberMember

    I thought it said for aquariums up to 70 gallons? At least that's what the blurb said.
     
  9. AlgonquinWell Known MemberMember

    Aren't most aquariums 'standard' sizes, regardless of what unit of measurement you are using?
     
  10. CichlidudeWell Known MemberMember

    Well the bottom line we are only talking about Mickey's Cashews here.
     
  11. AlgonquinWell Known MemberMember

    I have no idea what this means. you must be talking in Litres. :)
     
  12. Nick72Valued MemberMember

    Yes it does. That's the point - rated up to 70 US Gallons (therefore rated up to 265 Litres)

    Or is it: Rated up to 300 Litres (therefore 80 US Gallons)

    It's like saying a sports car will go 150MPH / 300KPH
     
  13. AlgonquinWell Known MemberMember

    I say ask Fluval. They will have an interesting time explaining this. Don't they know we have Calculators? :)
     
  14. SkavatarWell Known MemberMember

    70Gallons is not even a standard tank size according to this chart  
     
  15. Nick72Valued MemberMember

    It's not as though this would stop me buying a Fluval or even this very 306, but I just can't see the logic in quoting two numbers that don't equate.

    And I wasted an hour of my time, and a few minutes of each of yours trying to understand it. :)
     
  16. CichlidudeWell Known MemberMember

    But... but ... but... My 75 gallon tank has 2.5 gallons of gravel and I don't use the top 2.5 gallons of water. Therefore... 70 gallons!

    Maybe, but now at least you know that you're "not dumb", as per the title of this thread. ;)

    The engineers have nothing to do with the marketing dept who comes up with the literature and packaging of the box.

    I blame their marketing dept.

    Even @Cichlidude caught some mistakes on Seachem's website from what a I recall , and Seachem changed it.
