What Else You May Need
You only need a compatible aquarium that fits the stated 90 to 200 l content and 80 to 100 cm length range. Check that the tank layout leaves room for the protective basket and suction cup mounting.
Before You Decide
Confirm the aquarium’s volume and length against the stated range before choosing an offer. Check that the 20 to 34 °C dial range suits the temperature you want, and make sure the internal tank space allows the protective basket and suction cup fixing.
Planning Your Aquarium Setup
For a new or upgraded aquarium, it helps to decide where the heater will sit before filling the tank. The suction cup mounting and protective basket make placement part of the setup, so leave enough internal space around the chosen position and make sure the water level can remain within the stated operating conditions.
