frogspawn dyeing?

[spehhh]

ive had a pretty large colony of frogspawn for about 5 years now,ended up being around 40+ heads and in the past week they have started dyeing off and some are just really small. i thought it was a ph swing from switching salt but ph is good calcium is good alk is good salt is at 1.026 water temp is 75 new lamps about 3 months ago what else could it be??

I would recommend posting all parameters instead of good, this way we can tell you if there is a difference in opinions on what's good.

I had one that was about as old and large as yours. The heads were affected by the loss of light. As it grew the heads to the side and bottom would be shaded from the heads above and I would see some die off. Also it was so big it was getting close to the glass and probably being bumped by fish. I had to be careful when cleaning the glass. My parameters were CA440,dKH10,Mg1440,NO3 10/25ppm,PO4 .12 today.
