Water collection options

[Mortblanc]

You are still going to need an instant filtering system to use until the slow sand filter activates its bacteria culture and starts working.

If you use it before it activates it is useless and there is only one way to find out. Better to give it plenty of time to percolate before use.

Best to count on a commercial filter for a couple of weeks after filling the slow sand filter with its first water.
