So the 5 minute freshwater bath did not kill the Chaeto or the gracilaria. I’ll do a 10 minute dip now.when I grew Bortacladia for sale to LFS, GHA was my nemesis . So I would be interested in how long of fresh water soak to kill gha. Continue doing your test to determine lethal soak time required for different macros. Then attempt to find lethal soak time to kill nuisance algae.
I have salvaged Bortacladia that has been cleaned of gha by astrae snails & pods. I will research lethal fresh water soak time
after Christmas.
Please refresh my memory then.
I don’t have any hair algae though. I think all my snails keep it clean.
