[GSBN] Off topic question about water filtration

Hi all,

During my PDC with Rob Avis (Verge Permaculture) we talked about home
filtration and he suggested the Aquasana Rhino (he uses this). I have
done some preliminary research and have talked with a company
representative, but can't comment on comparisons to other systems.
Just thought I'd pass it on...

Cheers,
Christina

Use mosquito fish in the cold plunge and pool.

Last one of these I did (in Spain) we ran the water 100' to a join spring, well, rooftop and road runoff in a 365 m3 stone cistern for swimming and irrigation. We used the clearwater line to feed a level indicator that showed the 4 meters variation in water depth between full and empty with 1mm accuracy--you could see one bucket of water change the level of a square pool 10x10 meters in extent.

Ideally, I will be imbedding dataloggers/sensors in the walls of a strawbale structure as it is built and then be able to monitor temperature and moisture movement within the wall from the plastering process through several years of use. If anyone is familiar with specific brands or types of equipment that either works particularly well or should be avoided, I would appreciate hearing about it. Economy will unfortunately be a factor as funding for these monitors seems to be getting more limited each day.
