I have had my water tested by my chemist friend in the lab.
Water change due tomorrow,
N = 25ppm as N
P = 25ppm as P205
K = 80ppm as K2O
Is this ok?
Wet;47982 said:Are those measurements without or with dosing anything to the tank between the last water change? If dosing, how much of what between how long of water changes?
Wet;47982 said:How long have you been doing it that way?
That is high.
What are you dosing and are there plants?
I seem to recall you had a tap water analysis, could you re-post that?
Whoa, up pilgrim!
Do you have a cat pooping in your aquarium?
The nutrients are coming from somewhere.
How sure are you of the amounts you are dosing your tanks? This is where stock solutions and every other day dosing come in handy for the smaller under 200-gallons tanks.
Seeing those lab results says something is going on. Are all the fish accounted for? Are there any off smells?
Regardless, I think you need a very large, like 70% water change.
Do not worry we will get it sorted out, actually I think a good lab analysis would be helpful for a lot of folks, I know it helped me.

50ltr water change weekly

Also wouldn't be surprised by the numbers if there were any substrate ferts and/or no series of water changes after that recent uprooting of several month's worth of plants.
