Now you guys have me worried. I have a refugium with a DSB and an abundance of mainly Caulerpa and also a healthy ball of Chaeto growing in it that is attached to my DT. I started this refugium 15 months ago when I had a 300liter tank mainly because I battled high phosphates in the tank and also as a display tank with maybe one day seahorses. That was the plan!.
Have now upgraded to a bigger tank. Had the refugium linked to the new tank as well. It really works perfectly, feeding my DT with lots of little critters. The caulerpa is growing at a phenominal rate so I prune it back vigorously every week. I dont want the refugium to become to overgrown and scraggly looking as it doubles as a nursery for any small or new fish that needs more attention. (still dont have the seahorses, and dont think I'm going that way.... theyre just to fragile). The refugium is teeming with small copepods and other little critters.
What worries me now is this "going sexual thing" of Caulerpa! Any telltale signs that I can watch out for before this happens. I found the caulerpa growing at such a pace in comparison to the chaeto. Will cut them back even more to give the chaeto a better chance. And then for peace of mind go over to only chaeto.
