ROAR99 Posted July 4, 2013 Report Share Posted July 4, 2013 seen a few sumps with fine filter mat/dacron as the first media for the water to pass thru,, i guess because u can clean or replace that easier being on top without removing all the noodles/sponges. just wanted to ask do the noodles and stuff below still work as efficient with such clean water passing thru?

The Tech Den Posted July 4, 2013 Report Share Posted July 4, 2013 You could go that way or go a coarse sponge / jap mat first then a normal sponge then the wool that way your filter wool lasts a little longer. You can wash and clean the sponges $0 cost but if you are replacing the wool more frequently it add up. As for the noodles - it will colonise to the extent that the bacteria can feed and would still be more than enough as not everything is going to be captured.
