I think my lights are casuing GHA
ok so I bought my tank used from a reliable source. The lights I have, no idea of the brand. it sits screwed in on my canopy 90 gal.. 3 sets. the left and right side has all white leds.. the middle is a strip of 6 blue and white leds...
What I noticed is the GHA is extremely heavy on the left and right side of tank and hardly any in middle.. could this be my source? I think after my fluconzaole treatment I am going to reduce the white lights.. I really want to buy a couple new lights but each are $350.... heavy on wallet AM I on to something? water levels are fine |

Specific light spectrum can certainly influence algae growth..
As T5 bulbs tend to age you typically can tell as algae growth increases... stuff like that shows spectrum influences..

CBB lights half that cost.
Many don't like, I have had good success thus far with Visparspectra, not fancy, no software, no lightening storms, but built well and my corals, SPS, Clams, happy 25 months now. They also make a 30 inch, 350 watt model for 200 ish, might fit a 90 well.... Always make sure no sunlight crosses your tank. Last edited by Uncle99; 08/22/2018 at 07:54 AM. |

Some mount in canopy, some hang them
You will need a minimum of 14" from canopy inside top to water. If this is not available then stop here. A total of 4" for box(2.5") + cord (.5") + vent space (1"), and you will have to build a bracket to hold. This would allow the light to be 10" from the water surface. If you do not have fans already in your canopy, likely black box is not the way to go. So depends, if your ok at fabricating a bracket, if not, again maybe not the light for you..
