Hi, right left tap water standing for 24 hours and tested, came out at 7-7.5. have done a couple of large water changes over the weekend, last night tank was 6-6.5 so better. Will test when I get home again tonight. Have not managed to get a kH test kit yet. Hopefully tomorrow. All fish seem fine at the moment, no signs of stress. Have been watching them twice as much as usual over the weekend.............if thats possible lol.
