First off sorry if this is in the wrong place,
Yesterday I did my usual 60 - 70% water change, usual cleaning of glass, light hoover of debris of the substrate and a light scrub of hardscape. Added maybe 8ml total or milton spot dosing some pesky bba while the water was draining to make sure any run off got removed or watered down.
I also did a filter clean, cleaning the media in run off tank water reassembled everything and filled the tank back up with de-chlorinated, right temperature water.
Maybe 2 hours after being up and running a lot of my fish were struggling to swim or had already died. I lost 9 fish in total over the last 12 hours. Does anyone have any ideas as to why? Did I do too much of a water change? Or am I missing something? All the plants seem healthy and most of the shrimp (hopefully only lost one so far)
I tested the water after I noticed a few fish struggling everything seems fine value wise bar KH which is one colour to high on the chart.
Specs are:
Aquascaper 900
Eheim 600T
Co2 injected - correct levels
Kessil lighting on it's usual light cycle
If I forgot anything information please let me know.
