 Posted: Fri Jul 06, 2007 12:03 am Post subject: Green Algae in Live rocks |
 |
|
Hello,
My marine setup is two months old and I do water cleanup of 15-20% every month. My tank is in a place where no sunlight falls.
I recently noticed my live rocks are getting greenish in color and i see traces of green algea.
I want to know what would be the reasons for the same and how to control it?
Any suggestions?
Thanks
Kumaran |

Green algae is a sign that the nitrates in your tank are high.
Water change or get hermit crab ( indian ones are not reef safe) , but tangs are the best..
cheers !

Is lighting a problem I keep two of my lights always switched on it goes down only for 6 hours in the night and is on for the rest of the period.
Does this can be a problem?

Dont do a complete water change only about 10% though i would recommend the follwoing steps :
1. REduce feeding to fishes
2. Put a Bristle tooth tang or any cheap tang it will take care of green algae.
3. put hermit crabs ( indian are not reef safe though)
4. Put off the lights for 2-3 day and keep in complete dark.
Water change is the last resort always for green algae. |

Kumaran,
I would like to know when did you set up the tank and when did you acquire the LR to be put in the tank (did you use cured LR? or did you cure the LR in your tank?)
We should understand one thing here that a marine set-up with LR passes through five important stages which we frame as the break in period of the tank (in simple terms - cycling the tank) one of the stage is where the blue-green algae will increase and slowly die off as the tank matures further - now this is true only for a recently set up tank and not for any established tank so if it is set up a-fresh dont worry just keep good water circulation in the tank and if possible increase the menchnical filtration so that the suspended algae cells dont keep colonising other surfaces but get trapped into the media.
Now, you should also understand that what you read above is affected by other factors also as I said the prime factor is the time when the tank was set-up - the second important factor is good water circulation and correct lighting (you have also not mentioned what lights you use and with what intensity). another factor that affects this break in period is the source water that is used for making the sea-water if it is high in silicates the diatom phase will also be a prolonged one and thus increases the duration of the break in period. (sometimes the tank might take even 12-15 weeks to complete the break in period)
Madan had a thread which is made a sticky in the water chemistry section (it is a very good article by eric borneman)
you could read it
here
more on this when you provide us with further info about your set up |

Hi Kumaran,
I have answered your queries in the other thread - sorry for the late answer.
well, just for your information:
4000*K is indeed a pink light (rather orangish) so try to refrain from using it for a reef tank instead you could accomodate another coral blue lamp or something in the range of 14000* to 20000*K even an actinic will do.
6000*K is white light and 14000*K is blue light.
If the canopy is airtight try to open it up and till you open it up keep monitoring your pH.
I guess the use of sea-water collected near the beach is responsible for the tank taking just a little longer to cycle - so don't panic the algae will slowly vanish.
HTH! |
