I have a 330 penguin filter, The wheels were going a little slow, so i took it off, took it to the sink & cleaned it out. changed the filters, flushed the tube out. Then put water in the back of it & hung it back up, turned it on, & just when it started flowing, i realized, i had put tap water in the back, i was so used to doing that with my freshwater tank. i new as soon as it started i shouldnt off done that. how much damage have i done? I quickly turned it off & went to empty it. & did a quick 8gl water change. was that to little to late?
