Oceans Design carries the highest quality fiberglass tanks from our sister company Gemini Fiberglass Inc. Each mold originates from a high quality model which undergoes a long process of sanding and polishing. From this model a robust mold is made which can be used over and over each time providing a part with a smooth, shiny, gel coat interior finish. Through this process we are able to provide round tanks that are round, rectangular tanks that are square, and tanks free of mold marks and imperfections. The Gemini name has been recognized as one of the best tanks in the industry for over thirty years. If you don't find a tank that meets your size requirements contact us to have a high quality custom tank made per your specs.
