LED vs T5 Aquarium Lights side-by-side comparison. Pros, cons, when to pick each, and recommended setups for each tank type.
| Use case | Recommended |
|---|---|
| Reef SPS coral | LED |
| Reef LPS + soft | LED |
| Heavily planted tank | Both work; T5 if you prefer no shimmer |
| Budget reef tank | LED (long-term cheaper) |
| Show-quality planted | LED with high-CRI tuning |
Browse all side-by-side equipment comparisons. Or use the calculator collection to verify equipment sizing for your tank.
Equipment is where you allocate budget for stability. The cheapest pump runs hot + dies in 18 months; a quality pump runs cool for 8-10 years. The math on equipment is dramatic: a $400 quality canister filter beats four $100 cheap canisters across a decade, plus saves you the maintenance headaches + livestock losses from failures.
Three principles for equipment selection: 1) Oversize for the job - rated GPH is always inflated by 30-40%; size everything for the worst-case load. 2) Brand-name over no-name - established brands (Eheim, Sicce, EcoTech, Tunze, Hydor, Reef Octopus, Fluval) have parts available + service centers. 3) Plan for redundancy - 2 smaller heaters beat 1 large one (if one sticks, the other still works + the controller catches it).
For purchase planning, use our equipment budget builder, heater wattage calculator, protein skimmer sizing, and filter turnover calculator.
Should I buy used equipment? Yes for tanks + stands + plumbing (inspect for cracks). No for pumps + heaters + UV bulbs (unknown remaining life). Maybe for skimmers if you can clean + verify.
How long should equipment last? Quality heaters: 2-3 years (replace preventively). Pumps: 5-10 years. Skimmers: 10+ years (replace pump every 3-5). Filters: 10+ years (rebuild seals every 3-5). LED fixtures: 5-7 years.
Wattage vs gallons rule for heaters? 3-5W per gallon for cool rooms, 1-3W per gallon for warm rooms. Use 2x smaller heaters for redundancy + safety. See heater wattage calculator.
Sump or HOB filter? HOB for tanks under 40g (cheap, easy). Canister or sump for 40g+ (better filtration capacity, room for media customization). Sump required for 75g+ reef.
What about controllers (Apex, Inkbird)? Inkbird ($30-50) for any tank - protects from heater failure. Apex ($400-800) for SPS reef + dosing automation + Wi-Fi alerts. Worth every penny.
