algae and light

sharpie · Dec 30, 2006

i am leaving the lights off on my tank to try and help reduce algae. how long do you think it should take for green, purple and red algae to die if i only turn the lights on for a few minutes so the fish can see the food?
thank you

anyone?

I think it takes a couple weeks to kill the algae and I don't think you have to leave the lights off all the time, just reduce to 8 hours/day. If you have live rock don't you want to keep the purple algae?

Also recommend, if you don't have already, gettings some algae eating snails or other critters.

you can get rid of green algae with lawnmower blennies hermits and snails

the purple or coraline algae is prized so you wanna keep that

and the red algae it hight phostphate or organics... you can you 'red slime remover'

would lawnmower blenny eat brown algae and will it eat alga on med. crushed coral substrate?

a lawnmower blenny will eat algae off a ceaner shrimps;s butt, I have seen it!

Just a blackout won't find the cause of the algae problem in the first place. With out a cause, it will likely just come back.

It might, but really it's probable that the crushed coral is causing the algae. What are your water pram's like?
