I have to speak up. I've tried to not be confrontational, to accept everyones advice / comments / suggestions with politeness and gratitude. I am new to the hobby, but by no means am I stupid or uneducated, and I feel the need to speak up. Bob - please remove your blinders and read what the majority on this board are saying. Hooray for you, you have what you have, and you like it as it is. You shun tried and true logical advice dispensed by the likes of Kip and Thomas, who, in my eyes, are the heart of this community. If you are so closed-minded, you do not belong in a message board environment, because this is the arena for exchanging ideas and enhancing one's aquarium skills. There is too great a chance of a novice being subjected to your convoluted tunnelvision, and I hereby request you begin any of your posts with the following "My views are mine, and mine alone, and fly in the face of logic. Take my advice at your own risk". At least this will help the freshmen here know that there are other sensible solutions to their problems.
