I have my lotus sitting outside the pond,, to see if the darn thing grows,
before I climb into the pond with it...

it has developed a bad case of frothy algae ... I do NOT want to transfer
that yuck to my pond,,,,,,, so how do I get rid of it??
we used to get big boxes of stuff from the feed store, to de-algae our stock
ponds,,,,,, but I don't find the idea of buying a $30. box of stuff for 2 sq
ft of space.
