Sump light on 24/7?
 

Is it ok to keep sump light on 24/7? I have a 6000K CF "squiggly" wires direct to my tank's power line so it's on all the time. I know theres benifit at night, because of less PH swing, but is it ok?

do you have any macro algae in your sump? i have heard that keeping some types of calurpa(sp) in constant light can cause it go go sexual and kind of nuke your tank with nutrients. Cheato isn't supposed to do that though

around 2 years 24/7 with Chaeto here

Cheato, but GHA kinda molested it :(

i run mine on the flipside of my MHs so the sump is lit 18 hrs a day

Doesnt anyone remember grade 9 science class? Plants need darkness to photosynthesis properly, studies have proven this. You want the most out of your macro algea it needs atleast 10hrs of darkness with a 12 on /12 off pattern showing the most photosynthesis in plants.

chaeto ball, grapefruit to basketball size in 3 weeks, see no problem with my 24/7

what is a cheato ball
 

plz

just a bunch of stringy old cheato that has grown into a ball shape mine has grown across the rocks but it all does the sam ething

I am glad your showing good growth but growth doesnt mean photosynthesis which is what takes out nutrients.
