Will tilipia eat away hydrilla? I seem to have a problem catching bass because they hide in the hydrilla that has accumalated. what can I do to reduce the hydrilla, any suggestions, it seems it got really bad this past year. It seems I can catch bass at night but during the day they hide under the hydrilla unreachable. This is my guess. The pond is clear ,yes I need to fertilize but I`m afraid I`ll do it wrong and the whole thang turn into a mess. Any suggestions to cut back the hydrilla?
