Askoll Fluval U2

After spending months searching for a replacement at a reasonable price, I decided to make filter cartridges for this filter.

It was a bit of a long process because I didn't have the original cartridges with me. I lost them during a move.

These fit perfectly.

For the filter part, I purchased this sponge: https://it.aliexpress.com/item/1005007107817126.html?spm=a2g0o.order_list.order_list_main.15.19083696ZxOiuN&gatewayAdapt=glo2ita

Which I then cut to fit the cartridges.

I hope you enjoy the project and that it can be useful to other users.

Let me know in the comments what you think and any changes you might make.

Thank you
