To encourage growth in the aquatics industry, you can now post a job on the Aquatics Industry Board from Reef Builders. The price? $5. Why was this new service started? We were constantly emailed by small businesses, and large corporations that wanted us to post their job listings on the site. While we might occasionally highlight a few jobs on our main home page, we wanted to devote a separate section just for the industry and now we are lowering the price. It is only $5.
