jolt> yep, yun na nga eh, magulo yung mga advice sa net na wag masyadong malakas ang ilaw dahil magti-trigger daw ng algae bloom, pero di nila niliwanag na ang algae e efficient sa pagkuha ng ilaw, kahit ano pang wavelength yan basta PAR. (Photosynthetically Active Radiation)
i do understand the fact that old lights tend to give off spectrums suitable for plant growth (kasi yung blue dati, nagiging dilaw na.) pero kaya nagkaka-bloom dahil na rin sa mga compounds tulad ng nitrogenous wastes, phosphates at silicates. (an aquarist can experience algal blooms in his tank with phosphates as low as 1 - 10 ppb <parts per billion> regardless of light intensity)
btw, i've read that cyanobacteria can process phosphates more quickly than algae.
tama ka, yung pag-lilink ng intense lighting with algal blooms is nothing but an old wive's tale.
