Legot I'd also say that it's the black sand and maybe the height above the tank if they are different. Remember, black absorbs all wavelengths of light, and white reflects all.

In the end, the plants are getting more light than in the taller tank.

You have somewhat the same thing I had. The 20gal was in the "open".. Then it was put in a more enclosed area.. light looks a lot "darker" there..

Oh and yes white vs dark sand is not helpful

White sand will reflect the light a lot.

+1 on that!

Aquatic Delight its a marineland double bright. i'ts had at the very most 5,00hrs on it. all the leds have the brightness look to them.

it now has a black back ground, and eco complete on the new set-up as opposed to white sand on the old set up.

new tank


old tank



the photo doesn't really show it well, it looks a lot brighter in the picture than it does in person. idk maybe i'm just expecting to much of this light. i just figured that on a shallower tank the light would like brighter than on a taller tank.

Legot It would depend on the substrate and the background, is either darker in the 20L?

Is there any possibility that the driver could be damaged? Are any of the LEDs brighter than others? If it's still under warranty (IDK if they do that in this industry) send it in to get replaced and forget about the issue. If not then I'm sure we can figure it out.

About how long has it been running (like a rough estimate of the hours)? How many LEDs are there on the board and what wattage is the fixture?

Aquatic Delight i should have specified that the light is now on a 20l and not the 40b. which is why i am so confused. shouldn't it appear brighter on a 20l?

DaveK Consider that a 29 gal tank has a bottom surface area of 360 sq/in and a 40b has a bottom surface area of 648 sq/in, you can see that you have the same light trying to light up almost twice the surface area. I would expect the 40 gal to look dim compared to the 29 gal.

Depending upon what you want to keep in the tank, consider upgrading the lighting. You could either add an additional fixture, or replace the whole thing.

so i mounted the marinelandon the tank (5in above the tank) and the tank just isn't anywhere near as bright as the 29 was. and it doesn't seem to matter how high or low the light is it just looks dull.

any thoughts?
Probably an illusion.. When I first got back into fish I had a Marineland "puck" that I thought was fairly bright at the time.. When I bought my 40 and designed my own light, I moved the 20gal to a different location and put the same puck above it.. looks dull and really weak.. The light didn't change. My perception did..
