If you sump is big enough you never need do hardy any substrate cleaning, just change the white filter cotton every few months and that's it!!
Is it possible to still have bad filtration if your water test parameters show that things are normal? and good>?
why not properly set up the filtration you've got? When you are rinsing your sponges your likely damaging your beneficial bio media. You'll need to add some bio media to your AC filters. The bio media you can just give a quick rinse in tank water while the sponges can get a good cleaning.
