Well weird but 7 days into 3rd gen and the wash is still sweet as hell
The ph is low and the yeast is bubbling slowly
What u guys reckoning have tried to adjust the ph but its hard in a 200ltr fermenter to get it right will pay more attention to adjust when adding back slop next time

But it is 200litres of wash and a bit of a waste think ill right this one off as a fuck up and start a new gen

Why not dissolve 4 tbsp of citric acid in a cup of water and stir it in? Maybe some more nutrient?

Have you tried adding some nutrients? What exactly is your ph? What type of wash is it? I would be avoiding turfing 200L of wash if I could.

That's not going to help a low ph... Citric acid will make it lower.

Maybe break it down into smaller quantities and experiment with them.
Too much sugar?
Not enough nutrient
Etc
If you intend wasting it .... why not experiment and see what could be done?

One citrus acid is a buffer acid so it will help a little but given your low pH yes definitely put an alkaline in and raise the temp some how either a drum or box over it with a light in there or a spare lecky blanket or go get an Aquarium heater

some use bicarb, that works. I use hydrated lime coz I'm RAF but it works too :laughing-rolling: . yep a lot of guys cut the plug off , drill a small hole in the fermenter lid and feed the cord thought sealing it with silicon and re-attaching another plug. Others cut a big enough hole for the plug and re-seal with a slightly bigger plate and some don't give two fucks about sealing :roll:

Was your backset cool before you poured it in ? Didn't accidentally cook the yeast ?

You could get a paint stirrer on a electric drill and aerate the shit out of it , and Pitch more yeast if that doesn't help

Also a quick rock of the fermenter to just get some yeast back into suspension often wakes them up too.

Very common for home brewers to be out shaking the fermenters if the wash stalls. Careful tho - if it isn't ph and all the yeast needs is a nudge you might end up with foaming wash everywhere if the fermenter is too full.
