The easiest top off reservoir to refill is now here. Just slide out the easy to access acrylic drawer and fill it with up to 15 gallons of fresh water. Just put your favorite ATO pump in the reservoir through the pre-cut out opening in the back and you are ready to top off.

  • 15 gallon capacity
  • Slide out acrylic refilling drawer
  • Rear opening for pumps and tubing
  • Floating water line indicator

Most of the time ATO reservoirs are made up of 5 gallon buckets, or trash cans that are very unslightly and if they are stored in a stand, or under a table, refilling them can be a chore to say the least. Innovative Marine's Hydrofill Reservoir removes the chance of spilling, that uses a slide out drawer as a type of funnel, letting you refill without having to move the reservoir. The backside has a special cutout that you can pass through your favorite ATO pump, power cords, or tubing through.

Product Questions

Will a Neptune Systems liquid level sensor fit in the reservoir and which probe length fits, if any?
Question by: Lynn Peaslee on Jan 11, 2023, 8:59 AM
Hey there,
Thank you for reaching out to us. The 15" will fit, but you do not want the top to get wet, so you would only be utilizing half of the reservoir.

Please let me know if you need anything further and take care!

Will this reservoir work well with the Tunze ATO Osmolator 3155?
Question by: Andrew on Aug 16, 2022, 11:03 AM
Hello Andrew,
Great question! Yes, this works wonderfully with the Tunze Osmolator 3155. We actually run this combo here at the BRS office! Please let me know if there is anything else I can assist you with!
