ive just noticed my tds has creeped right up and my local shop has closed down so had to order some from pure freedom but ive got enough to fill half a bottle, would that be ok for a day or two untill my resin comes?

[SeanK]

Empty half the bottle and top up with your unused resin, the old resin will still work along with the new
making it last longer.

[Tosh]

Unless it's exhausted, in which case the old resin will start leaching crud back into the water.

[nathankaye]

The answer to orig question tho is a Big no!
The resin works as the water is forced through it. Only half full and you have slush, completely useless, hence the other suggestions.
However, what is your tds after ro??
I ask as there is no real need to be stressed about 000 tds. What is yours before it hits di?

[Shrek]

Is there an exact amount you should use? iv heard you shouldn't fill it full either- is 3/4 the ideal amount?

[duncan h]

No No and No
It must be full.
You will have to wait until you get some more

[SeanK]

It wont leak crud back into the water, I replaced my bottle yesterday which was half used and half new, I always get a fill
and a half from an 11ltr bag which I like to fully use before starting a new bag encase their are quality issues with the new bag.
Its no different than doubling up on your DI bottles, your not going to get crud going into bottle two.

Yes it will be ok for a day or two. It's exactly the same as using a smaller DI vessel- regardless of the tripe spoken on here.

I could be wrong but in Alex gardiners video for his 7ltr vessel , does he not say a 5ltr tub is enough?

Hi guys some interesting comments, I use double di after the tank, before I read this I went out and stirred up the newest tank and put it back in line and then emptied the old one completely as I thought best not to mix new and old resin, filled it half way and put it all back together.
Ran it through and back to zero on tds.
Hopefully I can get through tomorrow and my new bag will be delivered quickly from pure freedom, just need to not leave it so late next time

So your running a double di system and the slush mix is the 2nd di.    Do i have that right. Be interested to know ur tds before it hits that 2nd di tank and what ur tds is before it hits di.

As far as tosh's answers goes, its a load of tosh! It wouldnt be like using a smaller di vessel as the smaller ds vessel would compact it. Its the same reason why di vessel needs to be full, so it doesnt create gullies or runs in di, making you think di is used up, when in reality its by passing a good proportion of it. Thats why its recommended to tap down on ur di vessel periodically to eradicate this.

Well, I've read some B******x on here in my time but this is up there with the best of 'em!!

Take it from a 13 year Twin DI veteran Nathey boy, you're talking tripe!

Alex G says 3/4 full

So youve been doing it wrong for 13yrs , its ok to admit to a mistake, doesnt make u less of a man mate 
Curious, are you a ro plus twin di or just twin di lucky enough to have softer water.
If first option, curious to why waste money on 2 di and not one descent di.

[nathankaye]

An interesting link

Wonder how long a bag of resin last in both options. I know from my experience which option i would go for.

[ChumBucket]

I'm twin 11ltr DI only with a tap TDS of around 80-90pm

One thing I find with the riser tube in D.I. vessels is they can become blocked with resin and it doesn't take long for the TDS reading to rise once that's happened.

I clean the riser tube strainers with a toothbrush each fill. Like you say, the slits can get blocked with resin beads.
