Hi,
Need recommendation of a better 30L all in one tank(Filter, Light, IOS), currently I'm using KW390, it's a 3 in 1 tank (fan, Light, IOS) need to change it away. Reason: -over a period of time there will be water level mark which can not be wash away, suspect I need a glass tank (Main Reason) -the Top cover can not be removed. -The back of the IOS is fixed and I can clean it during annual cleaning. http://www.kwzone.com/products/links...20tank%202.htm Reason: -over a period of time there will be water level mark which can not be wash away, suspect I need a glass tank -The back of the IOS is fixed and I can clean it during annual cleaning. -the Top cover can not be removed. |

The water mark is mineral deposit. Even glass tanks will get it. Some people recommend scrubbing it with melamine sponge.
