Re: Aquarium lighting

Bigjd1988,
This may be useful info for you. If the "daylight" is 6500/6700K you have a good balance of light though in a 125 it likely is a slight bit less visible light
than you might want to have. Just a guess on my part about that aspect though. Seems to be enough for the Dwarf Hair grass according to this.

Re: Aquarium lighting

Both at 6700k lighting range. Or T5 unit. Depends on how fast you want it to grow.

Re: Aquarium lighting

There should be printing on one end of the bulb giving at least the manufacturer's name. If that label doesn't give the K rating then you
might Google it(the manufacturer) and see if the site gives that info. If no such info is available that way, you might just ask a Pet store
person when you next go there if they heard of that brand. If after a reasonable effort to find it out fails you may want to get two bulbs
which you know are in that range. A great price on that range bulb can be found at Loew's in a GE bulb marked "Daylight" 6500K.
Aquarium bulbs are usually much higher priced than these...cost me $8 in 18" but due to volume sales the 48" is cheaper usually.

Re: Aquarium lighting

I have a whole folder filled with scraps of paper and printouts that took years to acquire... and is a pain in the butt to sort through and find anything. Also a bunch of bookmarks in my lighting folder on my computer with many deadlinks inside... and you have made all that obsolete.

THANK YOU SUSANKAT!!!!!!!

Re: Aquarium lighting

Sometimes it is when the tank is short but it may not be enough in your tank without both bulbs being 6500K.
Put the grass directly under the light and see how it does. It might be enough.

They are the correct temp(6500K) so they should be fine.

Re: Aquarium lighting

PAR is really the standard of measure that is most accurate.
This is the most informative link to lighting planted tanks.
Lighting an Aquarium with PAR instead of Watts
It has some values listed for specific bulbs/or fixtures.

Re: Aquarium lighting

I am only going by research that I've done, I've not personally used these, so if I'm wrong I'll leave it to others to correct me. The "grow" (6,400k) would be good, but the "bloom" (3,000k) is out of the spectrum that is most beneficial to plants. If you want another to go with "grow", "finisher" (10,000k) or "super veg" (5,400k) should be good choices.

Re: Aquarium lighting

You can grow low light plants with both of those.
I actually have the first one you link on a 10g and although plants didn't grow much they certainly did survive for over a year before I stripped the tank for fry.

Re: Aquarium lighting

I am new to all this and have a couple questions if you guys dont mind. First, my tank has a single flouresant tube that im assuming is stock. Measures 23" from end to end and, looking directly at it, the light output apears to be white with a slight purple hue to it. I havent taken it out to look at the bulb for model numbers, but im asuming i could go with a better one when i decide to get some plants together.

So i just need to look for something rated for 6500k on the colour spectrum and higher wattage is better? Is there an efficiency to look for or is that moreso between the different types of bulbs (Flouresent, LED, etc)? And since im asuming this is a basic setup, can i get too powerful a bulb for my socket? Im just likely going to have some basic lowlight plants like amazon swords and java moss. Sorry for all the questions. Its a whole new world in the aquarium scene!
