Hi, so based on all the info i gathered it seems to be cellulose fiber de. A very tiny portion floats on top and for some reason doesnt get filtered. So,
i cleaned the whole filter and switched back to normal DE. Now i need to wait and see if it catches all the particles. If not i will buy new grids One question i had was, in order to facilitate the filteration of the water surface, i disconnected the vaccume (i only have one suction hole) and ran with only the skimmer on, basically. At higher pump speeds, this creates a tiny whirlpool (vortex like) and sucks everything in and once in a while makes a loud sucking noise, but and here is the question!
this also causes air to go in with the whirpool and hence i have ton of air shooting out of the jets. Is that bad for the pump or the system? Should i avoid doing that?
