Tank and filter

[axolotle42]

Hi so I currently have a 12½ gallon tank and the filter that came with it for my axie and would like to upgrade for when they get bigger to a 20 gallon long tank and sponge filter. Does anyone have any links to good ones or suggestions (UK)?
And also does anyone know of any good aquatic pet shops in Leeds, England?
Thank you !

I can't speak about sources in the UK, but here's the kind of sponge filter that I've previously used in both 10g and 20g long tanks without any problems. The sponges should be squeezed out once a week to clean them and replaced every 3 months. Just be sure you get the right size of new sponges. The nice thing about a double sponge system is that you can replace one at a time to help prevent the cycle from crashing. I personally like to replace the filter itself about every 6 months (they're pretty inexpensive, so this isn't a problem).
