cleaning filter grid

[essikr]

Thanks for the info ,I think I will go with the 1 to 20 ratio with the acid. I have the grid type element . Going to put it in the barrel and let it soak overnight . I really appreciate the reply.l

When I clean my grids, I use about 1 pint MA in about 3 gal of water. Never thought about what the ratio should be. I let them soak for about 10 minutes and brush them with a soft brush before a thorough rinse. That way, the reassembly is more fresh in my mind. The grids have always come really clean even with the short soaking time.
