![]() Whatever choice you make, you have to make sure the drain line can also handle the flow you want to put through the sump. Both types of drains are very similar in GPH (no real significant differences) and these types of drains are discussed in my example here the end of the article. With either set-up, one of the bigger factors to consider is the flow rates under extremely little to no pressure. ![]() There are many different approaches to achieving this, but mainly fall into one of two categories: Siphon based systems, or a Gravity system (which involves drilling a hole in your tank). Fresh water setups typically use a little lower flow rates, around 4 to 6 times the display tank volume is more common.ĭrain lines are the lines bring water down from the display tank into the sump. Some people prefer high flow through their sumps. The 10X flow rate is typically a good base to start working from and can apply to almost all typical salt water setups. Once you have determined the flow rate you will need, you will need to apply this target flow rate differently to both your drain line and your return line. Your exact flow rate could be higher or lower depending on the equipment in the sump or what you are planning to use the sump for. If you have a 120 gallon display tank, then that would mean you will need 1200 gph of flow. For example, most people feel a flow through their sumps of 10 times the display tank volume is suitable. Typically this is calculated in gallons per hour (GPH). With every system, you need to know how much flow you will need. ![]() The below applies to almost all of Canada and the United States. Note: you have to keep in mind, there may be variation in the plumbing products available to you based on the national building codes of the country that you live in along with local regulations, says Jet Plumbers Arvada Drain Cleaning Services. ![]() I will explain what I mean by each step then I will show you examples from one of my reef tanks All of what you are about to read below is based on my experiences with various data from some North American manufactures of plumbing products (IPEX, Canplas, and Boshart) which is also detailed in the American Society for Testing and Materials (ASTM) standards. I tend to think of it in flowing different steps: A) Planning of your flow rates, B) planning the material types and sizes, and C) installation / set-up of the plumbing system. This is not a very hard thing to do at all, if you focus on the basics and understand them. When you set out to plumb an aquarium set-up with a sump, the more planning / thought you put into the original set-up, the better it will be in the long run. ![]()
