What happen to the seagrape/green caviar

[tham64]

Hi Bro/Sis

I'm new in marine hobby, I have keep one 3'x3' refugium tank arround 3 months ago for my marine hobby start. In this tank I had kept two type of macro algae: chaetos and seagrape to remove the nitrate and phosphate. In this 3 months all the macro algae are growing fast under the sun. This night when I off the wave maker and on the T5 light to feed the coral, after 10 mins I saw the water has turn cloudy green. Then I realize there are some cloudy substance coming out from the seagrape torn like figures.

May I know who had faced to this problem before??? Just a few mins, the green seagrape had change to white grape....

This problem is due to the weather changers or other reason? Will it effect the water quality, and most of all will it harm living creatures?

I hope I will get some information from guru here.

Thanks Tham

PS: Sorry for my poor english :paiseh:

Your macro algae should be going asexual; it is adviseable to remove the dying portions as soon as possible and to place GAC to adsorb whatever nutrients it is releasing back into your water.

In order to prevent them going asexual, you can either do frequent trimming or to have them lighted for 24hrs.

For seagrape, when the colour change to dark green or some part turn to white... I think is a right time to trim. <_<

My angels and tangs love seagrape very much. Maybe can try to feed your fishes with it.
