Bubblefin Aquarium Sump Refugium DIY Kit for Protein Skimmer

This product includes 3 pieces of acrylic dividers for 20 gallon long fish tank. It does not come with fish tank. You will need to buy standard 20 gallon fish tank, and universal silicon glue from your local. Although the same tank manufacture claims the same dimensions for the same model for every batch, the actual inner size may be different from batch to batch. Take the sheet and try in store for the perfect one.
