Different generations
Fluval Plant 4.0 and Plant 3.0 remain separate
Plant 4.0 has its own controls and specifications. A Plant 3.0 profile is retained for owners; it is not silently replaced by a 4.0 model. The presence of a newer generation does not establish that the older one is discontinued.

Compare the current light choices or filter choices against your mounting and service space. This page does not declare a model discontinued without the maker’s evidence.
If the identity or condition is uncertain, use the used-equipment checks before powering it.
