dirty siphon hose...
How do you clean out a siphon hose, mine has black "stuff" in it and I certainly don't want to be introducing bad "stuff" into my tanks. After all the purpose of water changes is to ensure water quality, would make me sick if I made my communities of fish sick from weekly water changes.
Also, what sort of parasite might lift scales in a circular area on the body of fish. I've seen this from time to time and see one of my long fin tetras has a circular "knot" of raised scales. Fishy is ok other then that. It's in a 55 g, with one tetramin 70 filter, two bubbler ariaters, well planted and established for 3 years. No ammonia and the ph stays around 7.5, I do weekly 50% water changes, and I can't remember what other info you wanted before trying to diagnose. I can't do picts right now, (lost my cable). It looks like a small pebble was slid up under it's skin and makes it's scales stand out. Noticed this just today.
Any ideas will be appreciated! Thanks ahead of time.
