^ ignore the quote i read all your repliesYou are right about that, but I'm sure you know what I meant. I did put medium in parenthesis. It's the "Watts per gallon" guideline, I didn't come up with that. Sure it is rough (doesn't account for depth, or bulb length/type, for one) but it works very well in the home aquarium and there is no need to complicate it for hobbyists.
For your sake, we can convert it to "Lumen per gallon" and you can use it for LEDS, too. It equals to about 75 Lumen per gallon for low light, ±150 LPG for medium light and ±225+ for high light.
Using my new calculation (1050/10), you can see the 1050 Lumen LED would work very well in a 10 gallon tank.
Thanks for all the useful info. So you recommend t5’s is what I’m hearing. I know you said that bright to humans is not bright to plants so how bright are these lights to us? I want to assume they’re insanely bright to us but I know that’s not how it works.
three more questions if you don’t mind:
what are some other useful lights that you’d recommend (up to mid light I guess)?
Can my anubias regrow itself just from a rhizome alone? I know leaves are what absorbs lights so im wondering
Lastly how did my anubias manage to survive (and grow) for more than a year in the “dark”?
