How well does the HC hold up after a bleach dip.
I got a bunch of HC from my cousin and it was covered with alge.
Before planting them I wanted to do a dip to kill the alge. Has anyone done this, and how well do they hold up.
First, bleach is extremely toxic and does great damage over time to any life form including plants. If you correct the underlying problem - water chemistry is off, you will not have to go to such drastic measures. My water is crystal clear, no algae save for some spot which I like (on rocks) and algae is a natural part of nature... even the cyano bacteria is crucial in rice paddies in Asia.
PS sorry your plants came covered already. Can you trim much leaves off - these are small, fragile and bleach is extremely toxic (I am old school - Dr. Innes from 30's books from 50's and never had these problems)..... trim as much off as you can but leave root system and the strongest leaves so they can renew....
