LRs changing color

[searching4dan]

hi reefers..

i have seen LRs from many other reefers..

with algaes of reddish, purple, green..

but mine is turning brown.. brownish..

generally whole lot of them

initally i got my my LRs from another reefer

and the LRs are quite mature ones

with the purplish things (forgot wat its called) growing all over liao ..

but recently, esp after i got my T5,

i see a slight change in colors on my LRs

brownish, and if i pick it up and rub, a tiny bit brownish stuff will drop off..

is it algae oso??

can anyone enlightment me??

my water parameters are fine.. (if anyone of u are thinking to ask ..)

Browning only meant that algae is growing. Dose kalkwaser will bring coralline algae back.

Those purple/reddish looking algae is know as Coralline Algae and it is highly desirable. You have 2 problems at hand that need to be tackled one at a time.

Firstly, the brown thingy:

I suspect those are brown algae (or whatever you call it) and they are real bad! What lighting were you using previously? Is there a major change in intensity? What is the Phosphate level? To be frank with you, there must be something wrong in your system that promotes such growth... brownish algae is also common in new setups. Find out the reason why.

Secondly, the Purple Coralline Algae:

In order to maintain coralline algae, the condition of your tank must be right. KH, Calcium, Magnesium and Strontium (just to name a few). It can be a daunting task maintaining all these at tip top level just to grow some purple algae! There are 2 products I recommend you try. Caribsea AragaMilk and PurpleUp. You can find both at Reefdepot. You can read more at product review done by bro Altantis. I'm using both with very positive results. Actinic light also help in promoting growth (believe it or not).

If you are using tap water... perhaps that's the source of the problem.

Sounds like diatoms. They should go away with more time. If the live rock was taken out of the water for awhile or allowed to get too hot or cold, the rock will start another cycle in the tank from the die-off of small animals and algae that live in the rock.

Yes, Kalkwasser is a good source of Calcium.

Yes, dosing of Kalkwasser will also affect your other parameters... only use it if you are confident.

As mentioned before, if all you want is some nice coralline algae... stop the algae/diatom from spreading (lots of methods to achieve this) and can try Caribsea AragaMilk or PurpleUp. That will give you the purple you always wanted

will the aragamilk or purple up affect the ph,kh and other parameter????

[jervismun]

will the aragamilk or purple up affect the ph,kh and other parameter????

kH yes, pH not noticable... according to the product claim... these 2 products are natural products, there's no danger of overdosing... so far my tank looks decently "purple" after using them for 2+ months
