Species-specific temperature needs, seasonal adjustments, and breeding projects all call for a heater you can actually dial in rather than one fixed at a single setting. The Sicce SCUBA ContactLess line is an app-controlled submersible heater offering adjustable temperature control, across six wattages.
Why App-Controlled Heating
Different species, breeding conditions, or seasonal changes in room temperature all call for more flexibility than a fixed-temperature heater allows — ContactLess gives you that adjustability plus the convenience of managing it from your phone rather than a dial on the unit itself.
Choosing a Wattage
- ContactLess 50 — 10–15 gallon — the smallest in the line, with adjustable temperature control instead of a fixed setting.
- ContactLess 100 — 20–35 gallon — steps up wattage for small to medium tanks.
- ContactLess 150 — 31–45 gallon — sized for medium tanks.
- ContactLess 200 — 40–60 gallon — for medium to large tanks.
- ContactLess 250 — 53–75 gallon — for larger tanks needing more heating capacity.
- ContactLess 300 — 65–90 gallon — the largest in the ContactLess line.
Setup Tips
- Set your target temperature through the app rather than guessing at a physical dial's calibration.
- Match wattage to actual tank size rather than defaulting to the largest available.
- Verify with a separate thermometer after any temperature change, especially during the first adjustment.
