I cycled a 10 gallon with TSS+. It has been cycled for about a week. My pH was originally about 7.4 and GH was 5. I tested today and pH was 8.2 and GH was 7. I have added plants and MopanI driftwood in the past week. I have yet to do a water change. Is it the lack of water change that caused the readings to rise or something else?
