I just renovated my 23 year old pond and added a Savio skimmer. My water is beautiful and I love the job the filter is doing ,but I have noticed fish missing and find them dead in the filter. It makes no sense since they should be able to just swim back out of the front of the filter. The clerk at my local pond store seemed to think they probably died and were sucked into the filter..I doubt that because my fish all appear very healthy, the pond is balanced and the fish have been in there for over a month. Does anyone know if the water level can cause fish to be trapped in the filter? We have had heavy rains and the pond is very high. The water is above the level marked on the front the filter. To me that would make it easier for the fish to go back and forth, but so far I have lost 3 large beautiful fancy tail goldfish inside of the filter since the water level has gone up...:icon_sad:
