Here is what I see. Its a relatively new tank, only 3 months old, and its a 10 gallon so very small.
Its hard to maintain parameters in a 3 month old tank, but when you have 2 fish in a 10 gallon, the parameters will change every time you feed. Adding reef rods to such a small tank will have hige impact on phosphate levels. I don't think this tank has a skimmer, right? So its a big change to the system every week when you change the water.
Its sounds like a lot of tinkering in this tank in 3 months (adding corals, testing, etc...), the more you tinker the greater chance for error somewhere. Even forgetting to clean you hands can be a problem, much more so in a 10 gallon compared to a 50 gallon for example. Likewise, more tinkering in a small tank compared to large tank leads to more chance for error.
Torch is also one of the more finicky corals, compared to others.
I don't see any one or two things to change that will make everything suddenly happy again. I think you're still learning and your tank is still maturing and you are going pretty fast. Just my worthless 2 cents
