Hi Gary
Sorry about that.
Just logged in been tooo busy.
It is the blue tank, 5 years old.
It Is ready to start work , switch it on and your away.
You would need to buy resin as and when depending on use, a 25L bag of resin should be filled in the D.I .
There will be resin already in the D.I not sure about the ppm though.
Also not too often you would need to put the battery in the trailer on charge over night. Battery does not have to be removed, you just place charger in trailer.
A TDS monitor will also be of use to test the water quality as you may already know.
That is it basically.
There is a 45ft pole also which can be included if needed and all goes well, along with the 30ft already in the auction.
The trailer will work 2 people at the same time.
Hope this information helps, if you need any other info or want to view let me know.
Ade
