if someone would like to start a topic for plans for making a refug, sump, skimmer, etc. (separate topics for each would be great), and others will join in and modify it until everyone is happy about the plans and how to construct it, pictures, etc., we will be more than happy to have it at the top of this forum or we can put the different plans on an html address that people can be referred to. it's up to you folks.
