Brown Algae disappear during lights-off

[Oceandeep]

Just curious why the brown algae on DSB disappear every morning.

Currently my tank only have cleaner shrimp and camel shrimp...

Can any 1 explain...........

Thats good wat. Your 2 shrimps are doing a good job. I got 2 cleaner, 1 fire, 1 black sea cucumber, 1 goby, sea urchin, lots of snails and my sand bed still very dirty. All they do is relax under the rocks and wait for food!

the brown algae prob not beneficial to your tank anyway so its ok

[Oceandeep]

What about starfish?? Any try before??

[xiggie]

they are still there u will see them when lights are on ..

your brown algae disappears when the lights are off because algae are photosynthetic.

which is why when I had bad algae outbreaks a few months back, I did a complete blackout on lights to starve the algae of food. (=

If your so called "algae" disappear at night and reappear in the morning, they are cyno bacteria, not algae.

It means that you will have to control feeding as there are excessive nutrients in your tank.

If not careful they will spread like wild fire.

Agreed, it's the lights playing the trick.

its cyan... use redslime remover n rowaphos to counter the prob

Yo friend,

It could be that when your lights are off, all the cleaner crew critters like copepods, amphipods and tiny brittle stars come out to hunt and eat all the algae stuff.....

Thtas why it is cleaned up after your lights are off.

Remembering someone telling me before that they are dinoflagellates. Don't think diatoms or cyano will disappear just before lights off..
