I use a large plastic creamer container as my solids filter. I drilled small drian holes all through the bottom of this and drilled a hold in the upper part that allows me to attach it to the 1/2 in PVC that is draining into it. I bought some aquarium filter material from Petland for around $3 and I use nylon bath scrunchies and that filter to fill the plastic container. I clean it out twice a month but it could go longer. Clean out is easy - just remove from pvc and take whole filter to sink. I am trying to empty out another can so I can make a quick replacement filter. Take off old - put on new - clean when I have time...
