Micron rated felt filter bags/socks...

[robert]

I am going to have 10 (minimum order) pretty soon. PM me if you are interested to get some, I don’t need them all since they are very easy to wash and re-use. Measurements are 7"x16", 100 micron. I will be also getting 50 micron ones. I want to use these bags for sump inflow for tank vacuuming and water polishing when I blast my rocks with small MJ pump once every month or so.
