Hello, I have been reading that I don't really need to have carbon in my tank. I have an Deluxe Aqua-Tech 10-20 Power Filter (Purchased at Wal-Mart). There are 2 type of cartridges that fit into the filter. It says that one is a Biological filter (A hard sponge type) and the other is a Mechanical & Chemical filter (A cloth like on one side and hard plastic holder on the other side type). The second one contains activated carbon. Now my question is do I need to use the second filter as I have to change it every 2-3 weeks. When I do change it the cloth side is dirty. The last change was alittle longer then normal and the filter itself started to backup the water and overflow alittle bit. This is a HOB filter type by the way. With the bio filter it says not to change it but to just rinse it once in awhile when it starts to get dirty. I also have a UGF that has 2 tubes with carbon inserts. Was just wondering if I need all the carbon, if it will hurt to keep or remove the filter.
On a side note I have noticed that once I installed the UGF that my water looks alot more clear and crisp and the fish seem to like it. Not sure if they like the new UGF or that I just changed the tank decor around but they seem happier. It could also be that I think I got rid of a problem I have been having (Neons kept dieing and water was alittle cloudy). Thanks for any advice that may be given.
