I put two stacks of 2.5 inch hydro-sponge filters on the return lines of my two cannister filters. I did this to hopefully diffuse current and flow as well as removing more TDS.
I know water change is the best way to remove TDS, but any little bit helps, and the sponge filters are inexpensive and re-usable.

The air driven hydro sponge is in there so that it can grab the beneficial bacteria so I can use it to seed my son's tank.

Those filters you're using gets rid of total suspended solids (TSS) but not total dissolved solids (TDS) that are 2 microns or less. So, you would need a RO filter to remove inorganic or organic matter that small.
Thanks for the clarification Dave, I thought that might have been the intent but when I read "TDS" I wanted to double check. Wouldnt want novices misunderstanding how to lower "TDS" Total Dissolved Solids.
Mervin summed it up perfect .
