Introducing the Flipper Auto Top Off (ATO) - Clear Acrylic RODI storage reservoir.

Gone are the days of manually adding water to your tank. Aquarium care just got easier.
The Flipper Automatic Top Off (ATO) keeps your tank water level perfect using gravity (who doesn't love physics?). There are no floats, switches, or electronics that can fail.

Stable salinity is critical for a happy and healthy saltwater fish or reef tank. Freshwater tanks also benefit from an ATO because it's one less daily maintenance chore that has to be done. Regardless of the system, with the Flipper ATO, you can focus on what matters most (go ahead and take that vacation you've been putting off).

Ideal for Aquariums under20 Gallons / 75 Liters
Compatible on tanks between 16-20in / 40-50cm long 

Features:

  • Beautiful high-quality clear acrylic ATO 

  • Easy set-up with drip feed tube system

  • Perfect for fresh and saltwater tanks

  • Holds ~0.55 g / 2.1 l (RODI or distilled water is recommended)

  • Simple over-tank design that is gravity-fed - switch, valve-free

Feeding & Diet

An opportunistic omnivore, the Seahorse will scavenge detritus, uneaten food, and algae — making it a natural cleanup crew member. Supplement with small meaty foods like mysis shrimp or pellets 2–3x per week if natural food sources are limited.

Care & Water Parameters

The Seahorse thrives in stable, well-maintained reef conditions. Target parameters: temperature 72–78°F, salinity 1.025–1.026 SG, pH 8.1–8.4, and alkalinity 8–12 dKH. A mature, established tank of at least 20 gallons is recommended.

Reef & Tank Compatibility

Generally considered reef-safe. The Seahorse coexists well with most corals and peaceful fish. Use caution with very small invertebrates or slow-moving tankmates. Provide ample rockwork and hiding spots to reduce territorial behavior.

Size & Growth

Seahorses are typically shipped at 0.5–1.5 inches. They are slow-growing and generally remain small, making them well-suited for nano and mid-size reef systems.
