The Mag-Float revolutionary floating aquarium cleaner removes algae from your aquarium without needing to get your hands wet. Super convenient floating cleaner, cleans aquarium surfaces and floats when the inner magnet separates from the outer magnet.

Because you never have to reach into the aquarium, not only can you stay clean and dry, but also avoid toxic soap residue or lotions on your skin from getting into your aquarium water.

Secure auto top off lines, dosing tubing, and more to the rim of your aquarium or sump. These tube holders can hold up to 4 tubes and can be used as a set of 4 or be separated and used singly in different locations around your aquarium.

The Stingray is a 12-frag magnetic frag rack with key differences from all others on the market.

It all starts with the ModMag attachment system. Its rare-earth magnets are surrounded by ultrasonically double sealed ABS, making it reef-safe for years to come inside your sensitive saltwater environment — far better than brands that encase their magnets with glued together acrylic that leak, rust and eventually kill your aquarium animals.

The Stingray holds frags with its patent-pending Slide-Loc® technology. It grips your precious frags firmly so that snails, fish, or other critters cannot dislodge them – even upside down! One side of the rack finished in white. This helps reflect light to hit the undersides of branching corals like acropora — helping them grow faster and stronger. 

Also included is an adapter that lets you tilt your Stingray 30 degrees toward the light – allowing for more even distribution of light to the back sections of your corals.

But it doesn’t stop there, the ModMag that attaches the Stingray is also multi-purpose. It has slots, both inside and outside the aquarium, where a full ecosystem of optional accessories can be mounted. So your frag rack can also double as a camera mount on the outside of the aquarium, a nori feeder on the inside, or… Who knows what else might come since you and others can also take advantage of this mounting system with DIY creations or accessories from other 3rd-party makers.

The Next Generation of Magnetic Tube Holders

For years, reef keepers have struggled with poorly designed tube organizers that use glued acrylic holders prone to rust and failure. The MTO Magnetic Tubing Organizer changes the game with a durable, leak-proof, and modular solution for managing your dosing, testing, and return lines.

Rust-Free & Secure with ModMag Technology

Unlike traditional tubing holders that glue magnets inside, risking saltwater intrusion and rust contamination, the MTO features the ModMag—a double-sealed, ultrasonically welded ABS enclosure that prevents leaks and corrosion. The built-in «Shake-Test» feature lets you confirm that the magnet remains completely dry and safe, ensuring your reef stays protected.

No More Thumbscrews—Just Slide & Secure

Designed for Dosing & Automated Testing Systems

The MTO organizes up to 7 tubes—including 5 x 1/4” lines and 2 x 3/8” lines. It also features two guide tubes to keep automated testing system pickup lines, like those from the Neptune Systems Trident, positioned correctly to prevent air intake and debris pickup.

Whether you’re using frag racks, probe holders, camera mounts, or DIY attachments, the ModMag’s versatile sliding-slot design makes installation quick and seamless.

Stronger, Safer & Smarter Than Traditional Magnets

Unlike traditional acrylic-encased magnets that rely on glue and risk leaking over time, the ModMag Giga is ultrasonically welded and double-sealed, preventing water intrusion and ensuring long-term safety for your reef. The built-in shake test feature provides instant confirmation that the seal remains intact—giving you peace of mind with every use.

Customizable & Expandable with an Open-Source Design

The ModMag system is open-source, meaning it’s compatible with an expanding lineup of AvidAqua accessories as well as third-party and DIY creations. From frag racks and tubing organizers to camera mounts and feeding stations, this modular magnet is designed to evolve with your reefing needs.

Whether you are going to a frag swap, a trip to a local fish store, or just trading frags with other hobbyists, you always need a safe and easy way to transport your corals from one tank to another. The Traveler does just that!

The Traveler’s patent pending Slide-Loc® system firmly holds frags into place, even when inverted. The silicone-sealed, snap down lid creates a water-tight seal – no screw on threads to mess with or bind up. An insulated case is included that stabilizes water temperature and reduces vibration and shock to corals. It conveniently fits snugly in a standard vehicle drink holder or in the drink pocket of your backpack or sports bag.

The multi-purpose Traveler is also used as prophylactic dipping station to remove pests from your new beauties before placing them in your tank. One side of the rack is white making it easier to see and identify any coral pests during the treatment.
