hi!okay, last week i was looking for a diatom filter and one of the employees at one of my lfs said that he can sell me one of his for 60$, but he also said that buying a Wet Dry Filter Tray Pad would be the same thing as buying a diatom filter. is this true???he said that buying a diatom filter was just expensive because it was its own unit and didnt need to go in my whisper filter like the Wet Dry Filter Tray Pad did.Does anyone know alot about diatom filters that can help me out??should i buy one??or just stick to buying more of the Tray Pads??
