Long overdue an update so here is a short one.
The filter started the long fishless cycle on 3rd September.
Ammonia is clearing the 5ppm easy in 12 hours and has done since 10th October
Nitrites is off the chart and I'm so impatiently waiting for this to start dropping
Nitrate is off the chart too and I'm beginning to see brown algae in the water pipes
PH is a steady 7.6
Lets hope it's not much longer. It's my birthday in 3 days and it's a shame that the guests will only see an empty tank. Oh well, you can't rush it.
