Ah ok thanks.
I've already made up a litre by using the bottle label's instructions.I've no DI left to weaken it down to the right mixture so can i run it for a few hours until i get more DI tomorrow?
You can use it stronger with no issues just use it for the stated time though as leaving it in to long can have issues. Do not forget its a flush nothing more don't try and run you system fully with it.
