I am thinking about adding some grape caulerpa/c. racemosa into the refugium of my 15 gallon tank. I wonder if anyone can bring me a few sprigs of grape caulerpa.
I have a good amount of chaeto but they are not doing as well as I expect. They are probably getting too much light. Chaeto seems to like less amount of light than I have on it. They are bleaching at the top. When I set up my 180, I got too busy with it and my work was demanding, I started slacking off on water changes on 15G. Subsequently, when I put a new zoanthid frag into the 15G, it brought bryopsis in. Since then I am fighting a terrible battle with bryopsis in that tank. I tried many things including Kent Tech M, but increasing the amount of plants and light intensity and period in the fuge worked the best so far.
Interestingly, when I used GFO in the tank out of desperation, most of my c. prolifera melted away and bryopsis showed up in the fuge. When I removed GFO and increase the light level over the fuge, chaeto and c. prolifera recovered and started growing again. Instead of reducing the light intensity, I'd like to try some C. racemosa which grew really well in the fuge of my 120 in the past. C. racemosa seems to do better in very lean water and high light than chaetomorpha does.
