| Hi Barb
Your water is very similar to mine (surprise, surprise). However my Kh and Gh readings are reversed - Gh at around 300 and Kh at around 120-140. Sometimes sumi will go down and come back for the first 4-5 years and then settle. Sometimes it just goes down and won't come back. If this is a male fish, there is a possibility that it finished early and is just starting to decline. Mine is 8-9 years old (owner couldn't tell me when I bought her but thought she was 2 at the time). The last couple of years her sumi has been in decline but now seems to be holding but at a lesser quality than before. Someone mentioned something interesting on a different thread and I can't remember who it was. Only that there might be some trace elements or minerals missing in our water that would help the sumi develop better.
