Should I Add Ferts?

[jiffy]

In an attempt to revamp my tank, I bought some additional plants, reaquascaped, and want this low light tank to really take off. The tank has Java Moss, Java Ferns, Java Lace Ferns, Anubis Nana, and Potted Crytps.

The tank is a 10g w/ 1.5wpg.

I picked up some Flourish Excel at the LFS tonight, but I'm now thinking just the plain Flourish might be better.

The question is:
Should I add ferts?
If so, Flourish Excel or just Flourish?

Also, I should add that I am starting a job where I could be traveling M-F, 1-2 weeks per month. I know ferts should be added daily, or every other day, but if I'm not there I can't add ferts. Would adding them say, Mon morning, Friday Night, Saturday Night, and Sunday afternoon be OK?

Both would actually work. The Flourish will give you the trace elements you need, and Excel is a carbon suppliment, so it's kinda like having a liquid co2 tank.

In a low tech tank, I dont think you would need to add them daily. You are probably thinking of the EI method of adding ferts. IMO, adding them Mon and Friday would be plenty. could be wrong though. See what other people say.
