What does аквариумный mean, and how is it formed?
Аквариумный means aquarium as an adjective, literally aquarium-related.
It comes from the noun аквариум (aquarium) plus the adjective ending -ный. So:

In this sentence, аквариумный нагреватель means aquarium heater.
Russian often uses adjectives where English uses a noun modifier. Compare:
- aquarium heater in English
- аквариумный нагреватель in Russian
Why is it аквариумный нагреватель and not just аквариум or some other form?
Because нагреватель is the main noun, and аквариумный describes what kind of heater it is.
So the structure is:
- аквариумный = adjective
- нагреватель = noun
They must agree in gender, number, and case. Here both are:
- masculine
- singular
- accusative form that looks the same as nominative
So аквариумный нагреватель is a matched adjective+noun phrase meaning the aquarium heater or an aquarium heater.
