Planted Aquarium Lighting

Do aquarium plants only use red and blue light? Not quite. Green light drives photosynthesis deeper in the leaf than most hobbyists realise. Here's the light spectrum planted tanks actually use, why PAR and PPFD matter more than lumens, and where "PUR" marketing falls apart.

Twinstar S Series III sits at the performance end of Twinstar's lineup. It tends to be discussed mainly in terms of aesthetics and spectrum quality - less often in terms of raw output. This article looks at both, along with a practical PAR reference table based on our own measurements.

Reducing your photoperiod hasn't stopped the algae, and longer hours aren't producing better plants. Here's what sets the right light duration for a planted tank: why 7 to 10 hours suits most setups, when to run less, and why intensity and stability matter more than the number on the timer.
