Hi, I'm in Epsom so whatever supply central Auckland is on. I did another ph check today - don't know whats going on! Straight from the tap 7.8 today so checked some of my tanks - 1x ph6, 1x 7.8, 2x 6.4 and fortunately the one housing all my big males at 7.4. I think that seeing as they seem okay I had better not tamper with it.
Thanks anyway.
