What do you have under the floss to hold it up?I stop using socks....too much work on them...every 2-3 days new one, two time on month washing.... Now I have this and it is great...
Pic from assembling it, here missing on front lower part two holes for water exiting....
On front top go blue filter sponge and on top her white fine filter sponge....
Like this
Once a week throw that white filter sponge and put new and once a month clean a bit blue and put it back....
Much cleaner sump, works great....
