Anyone can help??
>Those are sludge. Will advise you to use your tank water to flush those particles out from your sump to maximize ur filter efficency. Those sludge adds additional workload to your filtration system. You should also look at the wool system. Seems like there the wool didnt managed to "catch" majority of the dirt. most cases there is a "opening" at the side (space btw the wool and the filter wall) which cause the dirty water to bypass the wool and get stuck in the filter media
