Hurray!

The LPS finally got in a shipment of plants, so I planted my 12 gallon shrimp tank yesterday(I've been cycling 2 1/2 weeks so far). This is what I planted: bacopa australis, Elecharis parvula, Hemianthus micanthemoides, pogostermon helferi, Rotala rotundifolia, marsilea hirsuta, alternanthera reineckil, hygrophilia polysperma, water sprite, cryptocoryne beckettili, and cryptocorne parva. I know that I'll probably have to do a fair amount of trimming. I wish I could figure out how to make the pictures small enough to load on here. I decided to use the picture of the tank as my profile picture.
Tank: LxWxH 16 x 14 x 14
Lighting: 2 20 watt GE Plant Aquarium florescents
substrate: GeoSystem Extra fine black gravel
Filter: HOB Aqua Clear with sponge on intake
CO2: DIY Hagen canister hooked up to a coral life wood stone below water column. (to push little bubbles back down)
I plan on stocking with Cherry shrimp in a couple weeks and I'm wondering if using Excel will harm my shrimp.

(I started dosing in my larger aquarium a few days ago). Also what sort of Ferts should I be using. I am currently using Nutrafin Plant Gro Iron Enriched and 1 Plant Gro Fertilizer stick. How often should I dose Ferts?
Might I add this is the first time doing a planted shrimp tank so any advice will be appreciated!
