All right, guys. No Mas! No Mas! It is gratifying to hear that my postings are helpful to members of this Forum. Sometimes it is quite difficult to present research-based information in a way that does not come across as "That Old Know-It-All'. In reality, I know very little, but I do have a talent for finding answers to questions that can be scientifically supported. Just think of me as a 'middle man'. I know that it can be very irritating to have someone regularly correcting another's postings, especially little things..But it is so very important that a Pondkeeper have the correct information, particularly as concerns the little things, as we all know grow into larger things. Anyway, I find this Forum particularly fulfilling and will continue to share until I am asked to stop..
