Frogspawn and hammer corals losing head

[Coleus]

The dying rate has been slowed down after i stop dosing vodka. My system is high nutrient that is why i was trying to dosing vodka to bring the level down. I think probably i dosed too fast at once instead let it drip.

HEre is how it dies

Mine did the same thing when I dosed coral snow.

re: your pH, say probe calibrated but think broken. Does the probe calibrate ok?

I never had luck with the test kits, but will trust my calibrated probe.

[Coleus]

yeah got the new one and now it is sitting at 8.0

Polyp bailout can happen when the coral is really stressed (from the vodka maybe) or when calcification is inhibited due to high phosphate levels or from toxins in the water released by leathers and algae conducting chemical warfare with your stonies. What is your phosphate at? Do you run any carbon? What is your water change schedule like?

[Coleus]

I tested my phosphate and it is sitting at zero. I have carbon and rowa phosphate reactor running. I change 10% water weekly. Leathers can produce toxin?
