Backyard Aquaponics
A place to discuss aquaponics

Hello,
My 11 silver perch have died over a 7 day period, also seedlings dying off after growing a couple of inches (chives, parsley, silver beet, carrots). The system is approx. 8 weeks old. Water is clear but has scum on the bottom.

Hi Tania,

We will need some more information before we can assist you.

What is the volume of your growbed(s)?
What media are you using?
What is the water temp?
What are you ammonia/nitrite/nitrate readings?
What is the pH?

Photos will also help.

Thanks I'll get that info & repost.

We might as well get it all at once,
Can you tell us about the cycling?
How long did it cycle?
With fish or with some other ammonia source?
What were the readings when you felt that it was cycled?
How long have the perch been in the FT?
Have they been feeding well?
Any noteworthy/changed behaviour from the fish?
And photos are super helpful

Cheers.
