Too much vodka?

[scotty333]

Is there a limit on how much carbon dosing you can add , I mean if you observe no ill effects?
I’m dosing 20ml in 525ltr tank , started 10 days ago with vodka
Nitrates are stable at 25 but wanted them down to <10ppm

Yes there is a limit. You will know when everything is coated in a lovely thick clearish white bio film. There are many write ups on this process. Phosphates must also be taken into account as well.

Po4 is 0.03

dont dose vodka if you have 25no3 and po4 0.03 - those numbers are fine.

And when stable perfect imo

no need to dose anything

Ok, if no3 stays at 25 I’ll quit the dosing
Cheers
