The HYDROS Control 2 is a small, general-purpose aquarium controller that performs the main monitoring and automation functions for your tank, letting you track temperature, detect leaks, monitor flow, and power and control equipment through the HYDROS App. It can run as a standalone controller for saltwater or freshwater planted tanks, or be added to other HYDROS Controls to build a larger system. The IP65-rated enclosure and HYDROS Safety Net help keep equipment and livestock protected.

The questions our support inbox actually gets.
Does it ship quickly?+
Orders placed before 2 PM ET on a business day leave the same day. Tracking is emailed the moment the label prints.
What if it's the wrong fit for my tank?+
Return it. 30 days, no restocking fee, refund to the original payment method. Better: tell us your tank first and we'll spec the system for free — half of all returns are sizing problems.
Who handles the warranty?+
We do. Everything carries the manufacturer's warranty and we run the claim for you — one email to us instead of a ticket queue.
How does the bundle discount work?+
Add items in the bundle builder: 2+ items saves 5%, 3+ saves 8%, 4+ saves 12%, and 5+ saves 15% off the whole system, applied at checkout.
