I'm sorry if this has already been asked but I just got home and I didn't feel like reading through 23 pages of this thread.
I have some thread algae in my betta's El Natural tank and although most of it is in the Riccia, which I plan on removing as soon as I get some more floaters, I do get the odd bit of it in my Ambulias and Cabomba. I know that Excel has worked for many to get rid of algae but what I would like to know is are there certain fish and snail species that are sensitive to Excel and which plants should not be exposed to Excel? Below is a list of the plants that I currently have in the tank.
I'll be getting some guppy grass and maybe some duckweed soon.
Below is a Crypt I have in there as well but I'm not quite sure what type it is so I'm hoping this picture will help. On the tag that came with it, it was called Cryptocoryne lutea but it looks different from the pictures I found online of it.
As for the snails, I have:
Brown and red ramshorns
Snails that resemble MTS only a lot smaller
I'd appreciate any help with this.
