thanks for the feedback. The only semi-dead thing i added was a piece of rock from the other tank that had been out of water for about 8 days. it was totally white compared to the other rock with minimal purple growth. Is the purple stuff growing on the LR coral algae?

When i took the readings tonight all was the same except for the HG which was up to 1027. I added a litre of de-clhorinated water and will take the reading tomorrow. Is it normal to see that much of an HG change in 24 hrs? I don't think I lost that much water to evaporation.
