We decided for night time number ones only, then it would only need emptying every other night so went for the larger capacity.
Actually, can I just confirm, we got it from gooutdoors with an Aldi over the road. So we got the chemicals from Aldi, am i right in saying blue in the flushing water, and pink in the waste bucket?
its not clear on the bottles as the pink one says its just a cleaner - confused!!!
------------- As a child my families menu consisted of two choices: take it or leave it.
Assuming Aldi's suppliers are using the same system as one or two other manufacturers, I think you'll find its the opposite way round - pink in the flushing water and blue in the waste tank.
(I've been using this "green" blue liquid for both)
We had a portapotty but it took up such a lot of boot space that we got rid of it. I actually don't mind a night time trip across the field, it's nice to see the stars!
