Shocking in what regard?
And yes on the leaves. Here are pics from that period.
im shocked about the ph, and how hard your water is and how you only feed them gold fish yet your fish are truely amazing... the auto water changer is deff doing them a lot of good since your nitrates are most likely zero if i had to guess... did you have the auto water changer when you had the oak leaves in the tank?... also how do you dose the tank for chlorine, chloramines and chloramides with the auto water changer? do you think they had better colors in the softer water? i would love to set up an auto water changer on my tanks.
