I will be doing that so I can filter my rain water before adding it to the fish tank. While relatively few people would want do use water from a small biosand filter in lieu of 'city water,' I think US folks could be persuaded to set one up so their pets can have clean water in case of a water outage.<br /><br />On the other hand, as slow sand filtration doesn't use chemicals, there may be some who would prefer use of biosand-filtered water over municipal water supplies...Meg Stouthttps://www.blogger.com/profile/01620672313029212529noreply@blogger.comtag:blogger.com,1999:blog-7555033592268651262.post-8405537997995061902011-05-22T16:28:45.454-07:002011-05-22T16:28:45.454-07:00Isn't that water storage tank the same as you ...Isn't that water storage tank the same as you have in your backyard? This past week has been very rainy and every time I passed a downspout I regretted that I had no catchment system in place. The biosand filter sounds like it should be in regular use to provide the best operating quality since drying out would be counterproductive. On the other hand, it seems that a faucet valve installed at the outlet is a good idea since research seems to indicate that leaving water in the biofilter for a little longer greatly improves the quality of the output.Okishduhttps://www.blogger.com/profile/03957104138287371004noreply@blogger.com
