Flourish Excel got rid of all my algae

Well I finally found a local source of Flourish Excel. I was in the process of adding it into my tank when my little girl ran into me from behind. Needless to say I dumped quite a bit in. At least 5 times the recommended doseage. 2 days later my bba, spot, and green fuzz algae is gone. No sign of it anywhere. I think I like this stuff!

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.

Limnophila sessiliflora
Cabomba caroliniana
Bacopa monnieri
Corkscrew Val
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
Pond snails
Snails that resemble MTS only a lot smaller
Zebra nerite

I'd appreciate any help with this.

Thank you!

Thank you Seattle_Aquarist and quatermass for your help. :)

On my stem plants, it's really not a whole lot of algae on them since I try to do my best to keep it at bay by removing it so would I have to double the dose for just a little bit of algae? As for the Riccia, I would be taking the plant out of the tank and treating it in a separate container. Quite a bit of it is starting to die anyway so I'd have to remove the dead bits.

Although I will admit that I don't like the thought that Excel kills off cyclops. I have a lot of them in the tank and that's my betta's live food source. He loves hunting for them.

As for the peroxide, correct me if I'm wrong but isn't that bad for a fish's gills? I thought it could seriously hurt the gills of a fish.:confused:
Yesterday, I took the time to read through this thread to see what other types of experiences people have had with Excel as well as doing a search on the internet and it has made me nervous. I've heard of people who ended up losing plants and fish from just the normal doses!

Call me a chicken s*&t if you want but I think I'm just going to try adding more floating plants to see if they can compete against the algae and I'll save Excel as a last resort. I'm also going to remove the Riccia, which I think is the real reason why some of my stem plants are getting a bit of algae in the first place. Could be wrong though.

Thanks again though for all of your help! I'm bookmarking this thread for future reference. :)

btw, that is a great looking tank, quartermass! What is that bushy looking green plant in the back corner of the tank to the right of the phone? I like the looks of it.
I wouldn't want to take the chance of adding other types of fish to the tank because of my betta. He's very territorial and mean and I know that a fish would end up getting hurt or even killed by him.

Since I last posted, the amount of algae on the stem plants has lessened.*knocks on wood* I keep getting in there to remove it and today I'll be getting some new floating plants so I can remove the Riccia.

That's my Riccia. I placed small clumps of it in between my Java fern leaves when I set it up and it's grown into those 'rounded lumps'. Every couple of months I have to remove it as it grows huge. I have a mere 11W overhead light on it. I sell the lumps to my local club. :)
I also have a bit growing on top of my filter outlet, Riccia turns a different shape leaf which looks rather nice when it's just out of the water. You can see this here - Riccia pics (Those are of my 250L tank with Riccia in it).

I also like the way the Frogbit grows its roots down so it touches the substrate.
I never would've thought to put some in between java fern leaves! That looks so nice and I can't believe at how different it looks above water.
