To Filter Not Not To Filter?

[fiskkeeperpro]

Hi,
I currently have a 12gal juwel rekord 60 with the internal filter. The pump to power the filter has broke and i just bought a koralia 1. The koralia 1 takes up quite a lot of space. Should i remove the filter and have 38x flow or remove one of my powerheads (not koralia 1) and have 27x flow and 30x flow when i get the new juwel pump on waranty?

I am also puting in a tupperware pot that holds cheato, if i took out the filter, could this pot have some filter floss on either side to catch some debris. I cant have an external filter so that isnt an option. I currently do 10-20% weekly water changes as i have no skimmer.

Thanks
Will

I'd fill the filter box with LR rubble and put the chaeto in with it and do DIY mod to get some sort of small light in there also, that way you can have your very own internal fuge! Id get the juwel pump in there as I do not think 38x flow is necessary unless you plan on keeping some hard to look after hard corals! 27x flow is more than edequate!
