    I have read elsewhere that some plants will die if you use Excel in their tanks.
    I thought it may be helpful to list the genus of the plants that this applies to.
    I only know of one for sure, so I hope other will add/correct to my list!

    1.) Vallisneria sp.
    2.) Sagittaria sp.

    Are you sure both Vallisneria and Sagittaria species get killed by the use of Excel? I have both plants and before I went pressurized I used Excel for a while with no observable damage to them.

    I am not sure, however I have heard reports about non-vascular plants being affected. I have witnessed a lack of growth, and leaf shedding in my tanks with vals.

    I'm going ask Seachem, and see what they say.

    i haven't noticed valisneria or sagitaria react badly to EasyCarbo (Excell).
    I have seen ceratophyllum demersum melt few times after dosing it but i am not 100% sure of the correlation.
    Few people on a local forum were sure that pogostemon helferi were melted by easy carbo, but on the other hand, i know a guy that has helferi growing like a weed with everyday easy carbo dosing so....

    Here is my post in the Seachem section of APC.

    This is why I am asking different people, because I hear it both ways.

    Maybe depends on how much you use. I was purposely overdosing excel to get rid of rhizo and my val nanas disinigrated in a week.

    Maybe a detrimental effect in aquatic non-vascular plants is dose dependent, time-exposure dependent, or both, since in my particular case I was extra careful as to not overdose and I only used it for a few weeks (5, maybe 6).

    This is another issue we could observe through experimentation... I'll likely test it myself.

    When I first used Excel, I double dosed it for algae irradication. I had a batch of Valisneria melt but, left the roots in place. In a month or so, the Vals grew back and were no longer affected by the Excel. I think it is just a matter that some plants will melt but will grow back and do just fine once they are acclimated. I no longer use Excel though. I use EI dosing, pressurized CO2, water changes and light reduction to fight algae now.

    Lot's of true aquatic plants will get killed by a full dose of excel, mostly non-vascular plants indeed. If you up the dose slowly and have patience most plants can adapt so they can use Carbo/Excel as their Carbon uptake.

    If you spray a 'fresh' batch of Riccia with Excel it'll mostlikely die. If you up the dose slowly and do not add that dose near the Riccia you'll be fine in a few weeks.
