Okay, so I have searched and searched and searched but I cannot decide on what to do. I have a 33 gallon tank with a HOB filter currently, however, the filter sucks and I don't think its really filtering much as it seems like the crud just gets re-cycled through. I don't know much about sumps or setting them up. I looked into possibly a different HOB filter or was curious at what my other options are for filtration that are effective?
. Using the salifert it looks dark pink from the side but merely a tint of pink if you view from the top.
