Re: Opinion on BIOLYTIX home waste water treatment I had an issue with the install and wrote to Biolytix to sort the problem out out. Yes, abosolutley no response which is a bit of a let down. However the system is now in to its second year and seems to be working well. The basic concept is good. Pity about the customer service. Some of the prevous comments may be right in that they are just looking for the money!!!!!
