Gen 2 Radion losing spectrum?
I have three gen 2 radion xr30’s. About 2 months ago I started getting hair algae. Strangely mostly under my middle light. I have three on my 180. Feeding has been the same, rocks were cured before setting up tank and nothing else has changed. Is it possible 5-6 years later the lights are changing and causing algae? Nitrates around 10, phosphate 0.04, alk 8, calcium 440, mag around 1350.
I am wondering if the light is starting to fade out causing the issue. What do others think? Sent from my iPhone using Tapatalk |

All light sources experience a spectral shift due to age..
Some quicker than others.. With Leds it tends to be much..much slower than MH or T5 Algae is fueled by more than just light though.. You certainly have nutrient levels sufficient of sustaining algae growth just fine too.. So.. Its certainly possible... Basically impossible to prove though..
