Hate to repeat myself (seem to do that a lot lately don't I?) - But just like anything else when its coming to plants and fish - ITS ALL ABOUT THE RIGHT BALANCE

Ah, I think I just figured it out... the bulbs that have a higher Kelvin rating will look more blue becuase there will be more intensity in the blue wavelengths (possibly to the point of 'overpowering' the reds/yellows/etc...), while a daylight bulb should have a more 'even' dispersion of power across the color spectrum. I think that may even be why I bought the Aqua-Glo/Sun-Glo combo - the yellow/orange 'peak' of the Sun-Glo filled in the 'valley' between the blue and red spikes in the Aqua-Glo's spectrum. I probably knew this at some point, but over-researched and confused myself...

Yea you can overread/ overresearch this matter lol thou it really is too simple for a planted tank; full spectrum 6500K on a t8 something 1wpg or less will do and one is set for a planted tank
The problem only then begins when people have a extreme in the tank (again the balance issue) meaning they have too much red light or only blue's or very very little light or hardcore high wattage....Its all about the balance

I think this will be my last update on this 'lower lights' thread; I will present some pictures that will quite clearly speak for themselves now

I will close off saying I am very glad I did this step and really only found positive affects on my tank with the lower lights incl the fish behavior (not just focused on plants here). Initially I was worried this would not work despite the math specially some plants (chainsword comes to mind first then Sag) I really was pretty certain they would not appreciate that change to 30w over a 55g standrad.
I took ya'll a few pictures because I am going to do quite some gardening tomorrow

I hope you enjoy the pic's and maybe I gave one or two people here something to think about when they want to update their lights that you do really not need high wattage to have plants thriving well

Just for the giggles I added a pic of this very tank dated dec 6 when I had first planted it (no plants where added to this tank since then only taken out )

That is just freakin' incredible!!! It's hard to believe it looks like THAT in 3 months time! I love how you arranged the ludwigia to be shorter in the front, and taller in the back...sort of stacking it. Beautiful job, Natalie! Hmmm, I might have to experiment going from 40w to 30w at some point...

That's what it is I can show you the org thread when I started building this one so you have a official time stamp on it
As I keep on saying its alllll about the balance

Yea actually there's a whole bunch of Pennywort hiding behind that Ludwigia too; not that you can see much of it any more now but it is there

I think your 40w will be just fine; I just hadn't found my 60 ideal and this I'm loving this set up now...

I HOPE some of the folks that initially sported me when I had this near-nuclear-meltdown with the 55g and all its algae and blooms and what not see this; especially the folks that told me to break it down and toss it all...this is a picture of what patience can look like

I totally remember you starting it. People were telling you that your DW looked like a ghost or a flame, etc. You kept trying to shift it so it didn't look like that. I wouldn't believe it if I didn't know it myself...it's just amazing. I'm so happy you were patient with it and it all worked out for you. You've got quite a show piece there!

nice, angel. i really feel like the less lighting i have, the better my plants do. probably because i don't have the other stuff to balance out too much light (ferts and co2)

thanks for the thread!

That's cool looking. And btw, I can see some Pennywort in that pic. You have to look but it's there. Oh God, I've turned in to a plant geek. Name association with pictures. I've gone so wrong in life (weeps)

Yep, we're all geeks, but in a good way!

Natalie, the tank looks simply awesome.
