Also posted to the UK group. Apologies for anyone reading twice.

After two power outages of about 3/4 and 1 hour, of my three tanks the
smallest (Juwel Rekord 60 with plants and 12 Platys) reads perfect water
quality.

The Juwel Rio 300 (plants, Platys, 4 Clown Loach, 6 Angels, 6 Danios, and 4
Corys) is fine except for the pH.
It's dropped to 6.0-6.5

My Rio 400 (Plants, Comets, Shubunkins, SAE, Tench, Orfe) readings were dire
!
Ammonia was high (4.0), pH had fallen to 6.0, Nitrite was 0.0, and Nitrate
was 40.
After a 40% water change pH was still 6.0, Nitrite 0.0, Nitrate dropped to
10, Ammonia 2.0.
I've now double dosed with Prime, so will have to wait 24 hours to read it
again.
Is the worst over, or are my fish doomed ?

As for the Rio 300, does it need a waterchange ?
The 2 smaller tanks have a 25% waterchange weekly (last Wednesday), and the
big one fortnightly (also last wednesday)

I am curious Peter. I have power outages some lasting an hour or 2.
I have never looked for tank changes and nothing has ever happened to
give me caution. What caused you to measure tank parameters after the
power came back on? Were the fish acting strangely? I never measure
chemical parameters unless I see fish behavior that needs
explaination.

I change 20% twice weekly in all of my tanks.

If it ain't broke don't fix it is my moto.
