lol my bad, ok 12kg going in

12kg in, we shall wait and see!

How long before I see improvents usually?

At least a week... and with current water temps... it will take a month to get on top off any parasitic spores floating around the tank...

Should begin to "pacify" the fish fairly quickly though...

They were already chilling as normal, just noticed they flicked on the side on initial takeoff as you saw in the video..

They're trying to scrape against the bottom.

I did a PH test - wow didnt know it could get so low to be ORANGE.
I gave it 2 cups of eco rose to bring the PH UP.

Getting some shel grid to hang in a sump tomorrow..

2 cups of ecorose is a lot.... how much did the pH move??

Remembering my water volume is 4500 in tank, prob 100 per gb (5) and 2 sumps..

Will test today

Hi all,

I've had a couple of random silver perch deaths.. 4 in the past 3 weeks.
Water readings are all good with exception of nitrates that are in the high orange to red range.

The fish are all fairly small still, 5-8 inches and its winter.

Should I put it down to just random ? Gills looked good. No visible reason.

I also have trout in the tank, wondering if maybe the trout are taking all the food.

Have you been seeing the Perch swimming around on the surface.. with raised/flared dorsal fin.... for a day or two before death???

No because its cold they school together at the bottom

I'm putting it down to a couple of possibilities.. A) trout are smashing all the food and they starve... B) too cold and they are too little..

Not much other reason
