i am not a retailer, I work for PM and we are just trying to clear out some space in the shop...these almost got thrown away but i repaired them so they could be sold. Ive built EVERY single PM sump for the past 6 years....the repairs are solid.

the diff between the BG30 and the BL30 is the bg30 has micron bags + a sponge and the BL just has a sponge.
