light intensity

In today's video we get with Taras and continue our series talking about lighting. Today we dive into brightness, specifically dealing with PAR and how it affects our aquariums. We cover both how light intensity is measured in the hobby and go over some tips and pointers when thinking about...

Hey everyone, basically as the title states, I'm new into the world of sticks especially Acropora's. Feeling comfortable that I have my system stability and parameters under control and consistently in line with the what we collective seem to agree as good numbers. Basically, no major swings...

Howdy, I need some help with my light schedule. We moved from having a BuildMyLED light bar to Reef Breeders Photon V2. We have a mixed reef of LPS/SPS and softies. But are not really getting the color on the corals that they should. We have tried different settings, and haven't found the...

I recently purchased a 16HD for my EVO 13.5. I was running my stock lighting for awhile but was getting algae growth from the intense white light. I bought the metal arm and its sitting about 10 inches above surface. I have 4 corals, a GSF, a ORA vargas cespitularia, A kenya tree, and One SPS...

Hey guys, one of my first questions posted, so apologies if I'm not following protocol to a 't', work with me here ;) Last Fall as I set up my first 4 foot LPS / Softy tank, I decided to pick up a Maxspect Razor for lighting, and have been super happy with the quality of the fixture to this...

Hi, I've noticed the underside of my birdsnest bleaching out. Is this simply due to a potential lack of light or maybe something else? If it's STN then I guess I can refrag as needed, but what about lack of light? Is this just an inevitability as corals grow out? Params are generally stable as...

Does anyone know where to find information about the solar intensity of the coral reefs throughout the year as the seasons change the amount of light the corals get is important to coral spawning and I’m trying to spawn some colonies in my tank with the help of apex’s season table, simulating...
