Skimmers

[Ruth]

I have 2 12g and 1 24g Nano tanks that I run successfully without skimming. Diligent water changes and rinsing of any sponges and maintenance of other media is definately required. I do run those expensive gadgets on my larger tanks but I know that some people have great success with no skimming on larger systems. I have not had that same experience so prefer to skim on larger systems.
