I raise plants in outdoor cattle troughs.  The troughs that get used daily get enough water
turn-over so that algae is not a problem.   The tanks with no water change-out  are trickier.   I
run my hands very gently over the leaves once or twice a week to sweep the algae off .   I also
have various fish in these tanks which control the algae to some extent.   At worst, I do a 90%
water change.  If you are using fertilizer, make sure the Phosphate content is low relative to the
nitrogen say (12-4-4).   Pond Lily fertilizer tabs are typically high  phosphate which promotes
algae.  Needless to say, don't overfertilize.
