Saltwater aquarium guide
How to Add Sand, Saltwater & Filtration to a Reef Tank
Updated 2023
This guide covers the one-time sequence for turning an empty aquarium into a filled, circulating system: place the finished rock structure, add sand, introduce prepared saltwater without creating a major sandstorm, install mechanical filtration, and start the heater and pumps safely.
If you are building the HelloReef 15, follow HelloReef Week 2 for the kit-specific water, salinity, flow, heater, and lighting sequence.
Complete the reef aquascape before it goes into the tank, choose the substrate with the saltwater aquarium sand guide, and prepare the water with the step-by-step saltwater-mixing guide. For the purpose and order of the filter components, use the saltwater aquarium filtration overview.

Step-by-Step Instructions
Incorporating the Aquascape/Reef Rocks:
Begin by crafting your aquascape outside the confines of the aquarium. Once it’s crafted to your liking, carefully position it on the aquarium glass. This approach provides a stable foundation for the rocks.
Introducing the Sand:
Use a generous cup or even your hands to distribute the sand evenly around the aquascape. Keep in mind that the sand will naturally settle more once water is added, so you need not fuss too much during this step.
Adding the Saltwater:
Arguably the most pivotal step in sidestepping a massive dust storm within your aquarium. Numerous techniques can achieve this, including a gradual water addition. Alternatively, you can use a colander and/or a plastic bag to pour water gently onto the setup.
Incorporating Mechanical Filtration:
Prior to activating your pumps, insert your chosen filter sock or sponge. This precaution ensures that any residual sand dust is caught, ultimately clarifying your aquarium. Additionally, this practice safeguards your pumps and equipment from potentially harmful dust particles.
Arranging the Heater:
A straightforward task involves placing the heater in your sump, rear filtration compartment, or within the aquarium itself. Concealing it from view is preferable, while also ensuring that it resides in an area with adequate water flow. Equally important, confirm that the heater is properly calibrated and maintaining your desired temperature.
Installing the Return Pump:
Your specific model will dictate the setup of the return pump, so adhere to the accompanying manual. However, essential to this process is ensuring that the pump is appropriately connected to the return plumbing.
Setting Up the Auto Top Off (ATO):
Much like the return pump, the ATO setup varies based on the model, so adhere to the provided instructions. Remember to procure an appropriately sized water container for the ATO, tailored to your aquarium’s dimensions. While a basic 5-gallon bucket is a reliable choice, more sophisticated options are available.
Additional Insights:
Once your setup is operational, conduct a thorough assessment of all components. Verify that there are no leaks and exercise caution by refraining from activating your skimmer, UV sterilizer, or lights during the cycling phase.
