My Tank Thread
My Aquarium Showcase
Decided to start a new post from the old one! Now its an emergency cause my freaking light went out on one side -.-
Anyway I hate to spend the money but I really do love my red sea 90 lights on my 70. That being said probably need 3 at 375ish each… OUCH.
The red sea 50 light is about 250 each. More in a price range for me. So my 90s on my other tank are SO BRIGHT and neither the blue or white are about 50% (actually both are way lower than that).
So this brings me to my question: can I get away with 3 of the 50’s for my 6 foot tank? Not really a science or math person so the explanations and graphs for the lighting are just confusing honestly. My understanding of the difference with the lights is the distance they cover and the intensity. Please correct me if Im wrong!!! So with me understanding it that way I reason that because I dont use my 90’s to full brightness I should be able to use the 50’s and get the coverage and stuff I need having 3 of them evenly across the tank.
Please help lol lighting is so not my forte.
I attached my tank below. And I know the type of corals is important for lighting too. Im newer to corals so Im trying any that I think are pretty and based on research I think I can help thrive! So if that helps Im not a SPS or LPS or any specific kind of tank, its all mixed at the moment.
