Green clean killing machine

[swissysrule]

So I have had my machine set up since last night. How many days will it take to clear my 29 gal. Of green algea? As of this morning I don't see a change yet. Thanks for any help.

Last time someone posted about this I think it took 3 days. It's hard to visually see a difference. Take a pic this morning and then compare tomorrow morning.

But you need to address the source of the initial problem too. Or it will just keep trying to come back.
