| Will the sumi ever come back up?
I have a pretty good shiro bekko that is hiding his sumi.
He's about 3-4 years old, and the second year had some decent sumi spots. Last summer it went down into the skin. You can still see them under the skin as grey shadows and each has a pinpoint of black that shows in the upper layer, but most of the patch is underneath. What are the odds that the sumi will come back up to the surface layer? Sorry I don't have a pic.
I've heard hard water can affect beni, but how about sumi?
It's a concrete pond, well matured, maybe 1,000 gal., and our source water is fairly hard also. pH is usually about 8, and KH is about 300, Gh 180+. 0 ammonia,0 nitrate, 0 nitrite.
10% water change(w/ cloram-x) about every 2 days(there's a slow leak), 20% with backflush about once a week.
Is there anything I can do to encourage the sumi to come back up? |
