I bought the pagoda fountain and loved it... until I opened a box of the replacement filters and they are useless. The original filter covered the entire space of the filter box and now the new filters have a huge gap! What is the point? Of course the water is going to take the path of least resistance and go through the gap and not the filter. POINTLESS! I may as well not use a filter. So disappointed and irritated since the boxes do not show the change until you open it.
