Marine Depot recently completed an overhaul to its Education Center, including new educational tools as well as streamlining the information all in one handy dashboard. Marine Depot has done a nice job putting together resources that are handy to the beginning hobbyist as well as providing features to help intermediate and advanced hobbyists as well.
Included in the revamp is connecting their forum, blog and article postings into the dashboard. While there are plenty of links around the old internet for calculators, Marine Depot had tied some handy ones into the new area with handy calculators for volume, sand bed, unit conversion and electrical consumption. The site also features a species information database and handy compatibility charts as well.
