Does anyone use this filter? I use it and have had it for 1 year now and was replacing the uv bulb, and when taking the old one out, I wanted to see if it still worked, and it did. Well removed it and put the new one in and it won't turn on, after trying different things and hooking the old bulb back up that just worked 10 minute before, it didn't work not either. I am really stumped on what to do. It isn't the bulbs, but it seems like its just not sitting down in there right? No idea. Looking for advice from anyone who uses laguna pond filters. Thanks
