Torch not opening

[sam-k]

Hi everyone,

I am facing an issue here, my torch stopped opening recently without any reason, all my parms are ok, my tank is 6m old.
Ammonia & nitrite 0
Nitrate 10
PH 8.3
Temp controlled through chiller 77-78
Salinity 1.025
Cal 500
Mag 1400
Any idea why?

All that looks fine. What about alk? Any additions or changes to your tank?

May need to look at your flow and/or lighting. How long have you had it? Could be getting too much flow and not able to tell how close it is to your lighting. Looks like LEDs.
7 dkh might be a little low with regards to your calcium and magnesium. Does your alkalinity fluctuate?

I am surprised as it was doing ok and open at the same place and suddenly not, my tank is the IM sr120 it got a good flow plus I have the MP40 on nutrient mode(low), also I have tried changing it location with no luck. For dkh am not sure if it fluctuates, am using the Red Sea test kit I had it 8 last week and yesterday it was on 7 I will re test again and will keep an eye, thanks.
