Niceone Dubb . Ive got a 1micron filter bag for filtering oil,s and stuff do you thnk ths would be ok to use

I think 1 mic would be to small to let any resign through.

Cheers for the responce SOorganic ...
I do not want it to let the crystal,s through i only want the water to pass through...
I can get a 1, 25, 50 or 100 micron filter bags easy alot easier than getting the money for bubble bag,s lol.
I thought 1 micron would have suited me best for the final wash of bubble

check ebay.. they will run you about $60 shipped for a set

Try gravity. Takes a bit longer and a bit more labor intensive but worth it. www.youtube.com/watch?v=neOVTsNr_D8
