Hey im converting my 55 gallon freshwater into a saltwater. Ive looked at different types of filtration and I realized I want a wet/dry filter. THey are way out of my price range and I plan on making one. I have lots of sites on how to build your own but I was wondering if anyone had instructions on how to make one out of a 20 gallon tub . I want to have a refugium wiht bio balls and a skimmer and heater in it.
Another question is can the biomatter ( bioballs) be submerged or do they have to be above the water line. Im fairly new ot the aquarum world and need some help thanks.
