    So to be clear, you’re not using a BSF at the moment it seems? You shouldn’t have issues with turbid water coming out of a BSF as they tend to be good at removing particulates. What I’d do is to keep your current filters as a post-BSF filter system, where BSF removes the larger particles.

    Never heard of a heater in sand before. For sure you’d need to protect the filter from freezing otherwise perhaps many of the microbes inside will die off. I’d insulate it very well and/or make an outhouse for it to keep the worst of the weather off. But in any case, in cold weather biological processes slow down so I would think the filter functions less efficiently anyway in terms of pathogen removal. But in terms of adsorption which will be a large factor in particulate removal, I’m not sure if that is affected as much by colder temperatures?
