Nothing to worry about the liquid carbon is gonna make ur plants grow a bit faster but do be aware wen u add more lights u have a higher chance of algae break out so jus keep an eye on you tank if u see algae growing jus cut bak the time they are on

Pedro hit this pretty spot on, the excel shouldn't hurt your tank and only help you plants, but doubling your lighting may cause algae issues.  If you see algae issues you can lower photo period, raise lights, run less bulbs and slowly increase it overtime.

Add a little radioactive uranium and you should be all set.

Be careful with the flourish excel. It's the only seachem producting with a "DO NOT OVERDOSE!" warning on it for a reason. I overdosed it once and it even killed my java moss.

i think i may have overdosed it because my lace java fern is starting to melt! I need to do a water change and cross my fingers hoping that i didn't ruin the plant! After a little googling, I found other people talking about the excel melting their JFs too. oops...

On the other hand, my other plants seem to love it!

I think slow-growing plants tend to be more affected by excel overdosing because they cannot absorb all the carbon. On the other hand fast-growing plants can absorb it and just grow faster assuming your tank is at least moderately planted.
