Easy there tiger. How many ritteris have you had?
Inadequate lighting takes months to kill anemones. Changes in water chemistry can be a big factor since the anemone is mostly water and has no barrier between it and the water around it. A slow change to 7.9 might be OK, an immediate change can be a problem. Low pH is sometimes a symptom of a high organic load in your water which is another thing ritteris don't like.
Most likely, as often is the case with anemones, it was already in a weakened state. The shock of one more change may have stressed it beyond repair.
Sometimes water changes and increased current around the anemone will help. If you can get it to eat tiny bits of food, that will help as well. Adding carbon filtration or changing the carbon in your filter helps to get rid of some of the organics and may perk it up too.
If you can get it turned around, then you need to get some better lighting, and good current.
