Customize Your Sump with Somatic
Start with an affordable sump/skimmer bundle then add on precision-fit accessories like dosing containers, a probe holder, and an ATO reservoir to improve the performance and capabilities of your filter system. Somatic's modular accessories can be added all at once or one at a time.
