Frogspawn RTN

[boxerzz]

I had it for 2 years , grown from 4 heads to 10 heads and more. Recently half of the connected heads on a branch started to RTN from the base. Then shortly after, another branch started. A week after another branch showing the same thing again. What is going on ?

The only thing that happened was a drop in Ca level (at 300), now it is slowly getting back up. My other LPS are same as before.

sg 1.025
Ca 380 ppm
Mg 1300 ppm
NO3 5 ppm
Alk 10 dkh

We once had a very large frogspawn begin shedding tissue for no apparent reason. Turned out the quartz filter on a halide shattered and the tank was being blasted by UV.

I am running T5 (it seems ok to me) and the 2 branches of frogspawn are at 2 ends of the tank.

Had the same thing happen on mine, new bulbs perked it right up! Now it's huge!!! Good luck!

Any ways to stop its RTN ? I saw a small area in the mid of its base showing its insides. This seems to spread out through the entire base until the whole tissue detaches from the skeleton.
