Ok so after tons of research about lighting a planted tank, I've come to realize that PAR is the only meaningful measurement. However, that requires a PAR meter, and I don't see myself investing in one of those for quite a while...
So, I found this site HOW TO Calculate your tank lighting ? Fishtanktv
I did the calculations and this article says I have "very low light" (assuming my math is right).
Can someone help me with this?
I have a low tech, Walstadish 75g long tank (48"x18"x20") and just went out and bought four 23w (100w equivalent, 1600 Lumans, 6500k) CFLs. My hood is custom made and has the fixtures already installed so buying a tube isn't an option atm.
Surely there's a way to figure out a rough idea without buying a PAR meter...right?
Included is a picture of my tank with the four CFLs for reference.
