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!

How about the rest of the life in the tank? Did they die too? Hmmm... Maybe my tank needs a little o.d. too

I would not intentionally dose five times the recommend dose, but I'm glad it got rid of your algae (I'm trying to figure this one out). Make sure to keep the tank in-balance so the algae dose not reappear. I hope none of the fish was harmed.

I should say that I got a similar experience.

I have a non-CO2 tank that has been clean for ages but the last 2 months or so I started adding Excel in a dose about 5 times the recommended about every 3 days.

Things were great no algae with the exception of very few bba spots.

After stopping the Excel bba, bga, and hair algae appeared.

I started dosing again and all 3 algae disappeared, only the bba is still there but less than before.

I was trying normal dosing of excel in my algae scape tank...it was effecting the cladophora as well. Now that I plan on trying moss instead of the clado, I'll be using excel to "clean up" the tank LOL.

Glad to hear this. I thought it was just my imagination. I have some kind of algae that I wanted to keep on my mopani wood because the otos graze on it. But if that has to go to get rid of the other nuisance algaes, then so be it.

I started adding just a regular dose of excel to my non-co2 20 long. Plants are growing better with it (especially my tiger val which dies off without it).

However, I noticed that my beautiful green, velvet algae that the otos like, is dying off and going black/grey. I need to start scrubbing off those dead spots as it is quite unsightly.

Has anyone had problems with their fish and Excel? I know that Flourish recommends a higher dose the first time, then a single dose therafter.

I would like to up it, but would like to know if anyone has had trouble with their fish.

The fish are fine. Nothing too sensative in there though. Cories, danios, a few white clouds. I added some rudolph and ghost shrimp (all we have in this area) and they are doing well also.

Doesnt beat up on thread algae does it?

Can Excel be used to combat algae in a CO2 injected tank?

plantbrain

If you consider adding CO2, that wikll clear up most algae as well.
If you add CO2 to low light tanks, that will do a very good job as well.

I can induce some algae and try it on a high light CO2 excess tank, but then it becomes difficult to say if it was the CO2 or the Excel hat caused the decline.

If you induce the algae in the tank(How do you do this with BBA without the CO2 issues?) and have log growth phase occurring, then add the excel=> dead BBA, then you might be able to say something causes it.

Otherwise you need to kow how t induce it without CO2 issues(limiting in a tank etc).

If your tank already has issues and you correct them and the algae goes away, then it's not any different than CO2 near as I can tell.

Make sure you have good nutrients/CO2, generally algae ain't an issue there. If so and you are certain(I never am) that those parameters are in good shape and you still have algae.......then add it at higher levels and see.

I've seen it/this occur as well, .......I ask why it occurs and also why the algae is there in the first place.
