Hi, I'm still relatively new to fish keeping but have acquired an Aqua One Equience cube tank that I believe holds 160 or 165 litres. I'm upgrading from my current biggest tank which is around 70 litres. I have only used internal filters before but as this is a larger quantity I'm thinking I may have to buy an external one for this. To be honest I would prefer to have an internal one if it would be good enough as I do lack space for one outside. I would appreciate some advice please on a suitable filter.
Many thanks.
Many thanks.
