Recently purchased a Scuba S1 and have been pretty happy with it. The only problem is I get extremely fine silt/sand left behind. I'm assuming this is too small for the 180micron filter basket it comes with. I'm not aware nor could find any replacement baskets so I'm thinking of getting 50 micron filter sheets (like what a fish tank uses, I think they call it polishing filter) and lining the inside of the basket with it. I was curious if anyone else has attempted this before regardless of the make of their pool robot?
