When designing the layout of your sump, it’s easy to plan for the equipment you have on hand, but it’s important that you avoid doing this. Instead, you should also plan for equipment that you may purchase later as you upgrade. For example, if you have a space saving protein skimmer with a tiny footprint, don’t make your skimmer section fit just that one device. Make that section a little larger, and keep in mind that down the road, you may go with a larger skimmer and will need extra real estate. This idea can be applied to the rest of your setup as well. Always leave yourself some wiggle room so that future upgrades are a possibility and won’t require much effort to pull off.
