How many hours a day should I run my aquarium light?
Most freshwater tanks do well on 6 to 8 hours per day, set on a timer so the photoperiod stays identical every day. Low-tech planted tanks rarely need more than 8 hours, and pushing past that mainly feeds algae rather than plants. If algae appears, cut back an hour at a time before reducing intensity.
Do I need a different light for a planted tank than a fish-only tank?
Yes. A fish-only tank only needs enough output to view the fish, so almost any LED works. Planted tanks need usable PAR at substrate depth and a full spectrum with strong red and blue peaks. Look for published PAR-at-depth figures rather than watts or lumens, since lumens measure brightness to the human eye, not photosynthesis.
Will an LED made for freshwater work on a reef tank?
Generally no. Corals with photosynthetic zooxanthellae need heavy output in the 400 to 480 nanometer blue and violet range at far higher intensity than plants require. Freshwater LEDs are weighted toward white and red for plant color and viewing. Using one over a reef usually causes pale, receding corals and encourages nuisance algae.
How high above the water should the fixture sit?
Mounting height changes intensity dramatically because light falls off with the square of distance. Six to twelve inches above the rim is a common range for mid-power LEDs on tanks up to 20 inches deep. Raising the fixture is the simplest way to reduce intensity without buying a dimmer, and it also widens coverage across the footprint.
Are aquarium lights waterproof and safe near splashing?
Most fixtures are only splash resistant, not submersible. Check for an IP rating: IP65 or higher handles condensation and spray, while unrated units can corrode. Always run the cord in a drip loop so water travels down and drips off before reaching the outlet, and keep the power supply brick off the floor and away from buckets.
Ready to decide? Our #1 pick for 2026 is the AQUANEAT LED Aquarium Light Full Spectrum (18-24 inch).
