What is the difference between clip-on lights, hidden strip lights, and aquarium hoods?
Clip-on lights attach to the rim and suit small tanks or simple layouts. But their beam can be more focused, so coverage may be limited on wider aquariums. Hidden strip lights mount under a frame or canopy to create a clean look with broad, even lighting along the length of the tank. Aquarium hoods combine a lid with integrated lighting, which helps control evaporation and splashes while providing consistent coverage, though they may offer fewer customization options than standalone fixtures.
Can one aquarium light work for both freshwater and saltwater tanks?
Some fixtures are rated for both freshwater and saltwater, but many are built for one variety, so check the aquarium type in the specs before you buy. Freshwater planted setups typically call for a balanced, daylight-like spectrum, while marine systems often emphasize blue channels and higher output, especially for photosynthetic invertebrates. Matching the light to your tank type helps maintain a balanced environment and a natural look.
