ferts and shrimps

[spirals]

ok soooooo i finally got the 28G up and running and its going to be more heavily planted than my other tanks. It's also my main display tank so I want it to be looking very very nice. While doing any sort of co2 injection is out of the question (for now at least) i did pick up some ferts at the store the other day. My question is : will they mess up my poor little ghost shrimp and random snails that will be in the tank??

They are API root tabs
(N): 3%
(FE) 5%
available phosphate 1%
soluble potash 1%

also maybe this is a stupid question but i'm tired and the brain isn't functioning:
it says " add 1 tablet for each 30 square inches of gravel surface" but then says a standard 10G tank uses 6 tablets....eh..i'll do the math tomorrow lol

thanks guys!

Anything that has a copper content carries a danger of being poisonous to shrimp. If it is listed as 1000ths of a percent, it is probably fine, if it's more then that, take caution.

Copper (Cu) is the main thing you will need to look out for. I know of a few people that won't deal with any type of metal in their fertilizers because of shrimp. So that Iron (Fe) bothers me a bit. But not so much. This article from planetinverts.com can give you a good insight on fertilizers and shrimp.
