Hi can anyone help me .
I,m doing a 21litre wash with 6kg of white sugar.And just bought a new fermenter and forget my hot water markings on the old fermenter, so how much hot water to add, and then cold to get the right temp to add my yeast .
cheers :think:

6 kg of sugar is more than you want for a 21 L wash, try to stay at 1 kg sugar per 5 L water maximum. Otherwise the yeast gets stressed and start making off tastes that carry through into your product.

As far as heating water, use as many lots of 1 L of boiled water to dissolve your sugar and then dilute to about 18 or 19 L with cold water and check the temp, if it needs more heat, add more hot and continue until you're happy. The amount of water you'll need will depend on your cold water temperature.

I don't bother with using boiled water, I just blast it all with the garden hose (dissolves the sugar and aerates the wash and takes bugger all time) and then use an aquarium heater to keep the temp just right.

Yeah thanks heaps for your help.
that sounds great using the air still at the moment, but seriously what to upgrade to the T500 but there's one problem I,m on tank water you know the story when anyone turns the tap on it stuffs up the flow rate to the condenser I know they put out a flow rate unit, but can you use a cooler box in my garage filled with water and a little ice and a submerged little pond pump Y/N what do you think. I purchased a mangrove jack heat pad to keep the wash happy and hope all goes well. :text-thankyoublue:

Yes you can but you would do better with a 200L drum

How does your tank water work is that for non drinking water and untreated

We are on tank water. Just get a 1000l IBC and recirculated through that. I filled it once and had lasted over a year so far

only use the tank water for cooling , not the wash I buy the good filtered water from the shop.

Thanks but , I know what you mean but doesn't the water go green on the bottom over a long period. :handgestures-thumbupleft:

What water flow rate per litres per min ,submersible pump would you recommend.

That depends on so many variables.
I use the Ozito 750W pump https://www.bunnings.com.au/ozito-750w- ... p_p4816360
But I have to go 15m and up 2m then the same back.
If your going shorter distance you could get away with the 350W
You could try smaller pumps but these seem to be absolutely reliable

Nah just put pond cleaner tabs in it. It’s only for cooling so doesn’t really matter the quality

Just watch you don't develop an internal leak in the PC or you'll be drinking your cooling water.

This is easy to spot though, you'd be collecting "product" (cooling water from your pc) before your still gets up to temp. More of a problem if the leak develops during a run.

:text-+1: I always turn on water with power besides safety this is exactly why :handgestures-thumbupleft: have devloped a leak before.

If you put pond cleaner tabs does that have any reaction with the metal in your still causing corrosion.

I haven’t had any probs in years and these go in our stock troughs so aren’t dangerous. It’s a minut amount. You can also just keep the ibc covered and you won’t get the green stuff, it comes from having access to sunlight

The ones at bunnings appear to have calcium sulfate (93 %) as the major ingredient and then a bit of diuron (less than 2%) and 5% sodium chloride. None of these will cause corrosion of the metal in a still (stainless or copper). It's possible the calcium could precipitate over time and build up inside your PC or RC. It's (calcium sulfate) solubility is 0.2 g per 100 mL at 20 degrees C but drops to 0.162 g per 100 mL at 100 degrees C (calcium salts buck the trend of most other ionic compounds). You may get calcium build up inside the condensers but it'd only ever be a tiny amount and never build up just in one spot (such that it causes a blockage).

The diuron is a herbicide that is a photosynthesis inhibitor that is considered harmful to humans and has US recommended exposure limits of 0.01 g per 1000 L. I'm pretty sure I don't want this ending up in my product in the event of a leak happening mid run. :handgestures-thumbdown: but again, if you had lots of cooling water then it might be ok. I run on about 20 L of cooling recirculating through a radiator, so I'm going to steer clear of this stuff.
