Radion RMS Track 70.5 in. - Multi-Light Aluminum Rail Aquariums 68-78 in. - EcoTech Marine

The EcoTech Marine Radion RMS Track 70.5 inches is the longest track in the range available at ReefSolution. Anodized aluminum horizontal rail that runs across your aquarium between the two RMS arms (Arm Pair), this is the "B" part of the Multi-Light RMS modular system. This 70.5-inch (179 cm) rail is suitable for aquariums from 68.5 to 78.5 inches in length — designed for large 6 to 7-foot reef aquariums, including Red Sea Reefer 750s and 220+ gallon systems.

Track Length Guide — Which track for your aquarium?

RMS arms extend 3 to 4 inches beyond each side of the aquarium. The track should be chosen based on the total length of your aquarium. Here is the matching guide:

• 20.5 in (52 cm) Track: 18.5 to 28.5 in Aquariums
• 30.5 in (77 cm) Track: 28.5 to 38.5 in Aquariums
• 40.5 in (103 cm) Track: 38.5 to 48.5 in Aquariums
• 50.5 in (128 cm) Track: 48.5 to 58.5 in Aquariums
• 60.5 in (154 cm) Track: 58.5 to 68.5 in Aquariums
• 70.5 in (179 cm) Track: 68.5 to 78.5 in Aquariums — this product

The track is adjustable front to back on the arms. Even if your aquarium is not a standard length, choose the closest track — the system adjusts.

Typical Configuration for a 6 to 7-foot Aquarium

A large 72 to 78-inch reef aquarium typically uses three to four Radion XR30s for complete PAR coverage across the entire surface. Recommended setup: 1 RMS Arm Pair, 1 RMS Track 70.5 inches (this product), and 3-4 XR30 Slides. For a mixed reef, three XR30s provide excellent coverage. For the most demanding SPS, four XR30s or a combination of XR30s and XR15s at the ends ensure high PAR in every area of the tank.

Parts required for a complete Multi-Light system

Frequently Asked Questions

Is the 70.5-inch track suitable for a Red Sea Reefer 750?

Yes. The Red Sea Reefer 750 measures approximately 72 inches (6 feet), which falls perfectly within the 70.5-inch track range (68.5 to 78.5 inches). This is the recommended track for this aquarium and similar 180 to 300+ gallon systems.

How many Radion XR30s can I mount on a 70.5-inch track?

Three to four Radion XR30s can be installed on a 70.5-inch track. Three XR30s provide full coverage for a mixed reef. Four XR30s provide very high PAR for demanding SPS-dominated aquariums. You can also add XR15s at the ends to fill in corners.

Is the RMS track the same for XR15 and XR30?

Yes. The track is universal — it accepts XR15 and XR30 Slides on the same track. The difference is only in the Slide model used. You can even mix XR15s and XR30s on a single track.
