So my tank has been up for about 6 weeks now. The other day I had to get under it to do some maintenance I noticed that I had a lot of "stuff" at the bottom of the overflow. The LFS told me to use a stand pipe so the water didn't have to fall all the way to the bottom of the overflow making too much noise. I did ask if I should fill in the open space with bio balls or something similar.They said no. Over time this "stuff" will surly build up to intolerable levels.Should I have added some sort of space filler or do I just have to plan on cleaning the over flows? Basically it is unfiltered waste and excess food.
