oh no. it would be too expensive and messy. use a biocleaner. its cheap and easy and fits in your lagoon. after the 3 months. just lift it up and store till next year,
the water could then be recycled for any number of uses. super clean.
and if you are in the vicinity of Melbourne, you could just rent it for 3 months out of the year.
super cheap
