I have had my tank about a year now and was wondering if there is any maintenance I need to perform on the hoses going down from the overflow to the wet/dry filter.
I ask because lately the hose that goes into the wet/dry filter seems to be making a gurgiling noise every once in awhile. All I can think of is perhaps it's because the hose that goes from the overflow to the wet/dry filter is slightly curved, so maybe the water builds up in the hose until gravity takes over and pushes it into the wet/dry filter.
In addition, the light that is usually on, on my uv sterilizer hasn't seem to come on in awhile. There was a light on the bottom of the sterilizer that was always on, although there is still water being fed from the uv sterilizer into the center chamber of the wet/dry filter.
I'm going to take some pictures really quick and post them
