So today I was having a good look around the tank and I noticed one of my Montis had turned white. The polyps have completely disappeared around the base and on a couple of the branches.
I have quite a few variations of Montipora and none of the others have this issue. I’ve had this Montipora Digitata coming up to two months now. It’s in the highest part of my tank and is in a high flow area.
I’ve looked around online and discovered there’s pests such as nudibranch which can cause this…… I’m really hoping that’s not the problem! So I’ve ran as many tests as I can and I’m also checking the tank quite often whilst all the lights are out to see if I can spot any nudibranch pests.
Most Recent Parameters:
All test kits are Salifert apart from the TMC Refractometer
Temp: 25 Degrees C / 77 Degrees F
Salinity: 1.026
PH: 8.3
Ammonia: 0
Nitrite: 0
Nitrate: 1 (a little lower than I’d like)
Phosphate: 0.03
Alkalinity: 8.3 DKH
Calcium: 430 ppm
Magnesium: 1470 ppm (I’m currently trying to lower this to 1350, I’m still making adjustments to my auto dosers)
Strontium: 16ppm (I’m also auto dosing this and have just decreased the dosage so it hovers around 10ppm)
Iodine: 0.06ppm (I use 1 drop of Lugols Iodine a day)
Any help would be greatly appreciated, I have so many montis in my tank and I’d be gutted if this is going to happen to them all.
