Does in sump LR need light? - Aquarium Advice

swissfish · 12-28-2004, 05:00 PM

If the answer is yes, how much?

the purpose of live rock in a sump is for bacteria for the nitrogen cycle. These organism need no light to survive.

thank you, thats what I thought but wanted to make sure.

mattmku is right on the bacteria. A lot folks will also put algaes in their sumps for additional nutrient export. These, obviously, would need some light. But you could easily get away with a simple 20watt [acronym:4246355213="Normal Output Fluorescents"]NO[/acronym:4246355213] fixture.

What I did was to put my lights on a timer opposite my tank lights, I may not need it in my sump/ref. but it keeps my [acronym:8427546054="Oxygen"]o2[/acronym:8427546054] level even. I was told once that your [acronym:8427546054="Oxygen"]o2[/acronym:8427546054] level drops like a rock when you turn out the lights so I put the light in. I have 2 40 watt "grow" lights for my sump.

i have lots of lights on my sump. i figure the more plant life, the more oxygen. i like the idea of oposing the light cycle to keep [acronym:5d24a1ef10="Oxygen"]o2[/acronym:5d24a1ef10] levels even. thats really cool

Sorry guys, me and chemistry

What has light to do with [acronym:e4f3224edb="Oxygen"]o2[/acronym:e4f3224edb]?

foma2000 · 12-29-2004, 12:57 AM

when the plants are well lit the plants take in co2 and put out [acronym:d4983eede0="Oxygen"]o2[/acronym:d4983eede0]. during the night they stop producing [acronym:d4983eede0="Oxygen"]o2[/acronym:d4983eede0] and even release a small amount of co2. therefor, durring the night (or when the plants arn't lit) there is a large drop in [acronym:d4983eede0="Oxygen"]o2[/acronym:d4983eede0] levels.
