| I get it bil. Sounds good. Since SMG's gets to remember stuff, so do I. About 1995 someone on one of the long-forgotten koi boards told me about using nylon stockings for mechanical filters and about using a cannister of compressed air to help backwash and re-segregate sand and gravel in a mixed media filter. I think that was you. Used both of those tricks here and there along the way and both worked as advertised. A belated thank you. steve hopkins |
