3ft tank for Goldfish

[Ghostrider]

I want to upgrade to a 3ft tank for my goldfish. 12 goldfishes too cramp in a 2ft tank.
What model of the Eheim filter is suitable for the tank (prefer external type?
Which LFS can I view some sample of 3ft tank and stand?

I am currently using a Eheim 2026 ProII for my 3 ft tank.

i used to keep 6 ranchus in a 2'.
i used eheim 2226 and i still have to change 80% water every fortnight.
so i think is advisable to get one which has big filter media compartment.

goldfish are poo machines
plus i dont think you will have plants inside.

so for a 2 ft,
i will recommend
2217, 2026 or 2226 as minimum
2028 or 2228 all the better

and a fortnightly water change is not too frequent at all!

i have some tanks i need to change water like once every 3 days.

it is very easy unless you are using buckets!
if you are...well...change to hose!!

**tip: attach a J shaped pipe (eg eheim inlet pipe that hooks onto tank side) and not only you dont have to worry abt hose falling out, the water will stop draining by itself once it reaches a certain level
