The latest water testing results show that oxygen levels are improving slightly (6.5 mg/L, and 59.3 % at 10.4 °C); this is likely to be due to the lower temperatures and bad weather that we have had recently. We have, unfortunately, seen a small up-tick in ammonia levels (now at 0.3 mg/L, pH 7.8).

All test result charts can be found here, if you’re logged in as a member of the club.

Jim’s invertebrate monitoring spreadsheet has also been updated for November.
