I shall be re-ordering Muck Munchers for the coming year; however, I was wondering if it is good practice to re-order the booster pack that I got with my first order last year. The sachets have been such a resounding success that I would hate to knock the balance by omitting to top up with a booster if that is advised. PS – A very Happy Muck Munchers customer – for life. A note from Bio-Gard – We continue to send renewal packs with a Bio-Booster Pack. This may be used to simply boost the septic tank when received – or – retained for use after a pump-out (which we hope should not be necessary).
