We will sell this macro in billiard ball sized portions. Ulva can be found in large sheets, or growing like a crumpled up piece of paper. Sea lettuce can be placed in a sump as a nutrient exporter or in your main tanks as a treat for fish. Ulva can also be placed in a main tank for beauty. Be careful, it is tasty to any fish. In the sump, it is great for growing your pod supply. Pods congregate in it like a letter in an envelope. Due to your mission, you are welcome to inquire as to what state we are finding: sheets or crumpled. Those crumpled green pieces are especially beautiful.
