It is not Hygrophila Polysperma.

Looks like it could be some sort of Sagittaria, but not sure, it could also be the dreaded modo grass which is not aquatic but pretty much sold at all big box petstores as an aquatic plant.

Ophiopogon japonicus, AKA mondo grass. It is not an aquatic plant and will not survive long-term in an aquarium.

Mondo grass? If so, they screwed you, it's not an aquatic plant and will rot in no time. Can you return it??

It's not dwarf sag, the leaves are too long, too thick and don't appear the right color.

At first I thought it could've been a for of Sagittaria or Mondo grass, but I am pretty sure if it is a Sagittaria it is not dwarf Sagittaria.

Just really hoping it's not mondo grass that's all.

Yeah that is a good idea! Unless you need some plants for your patio =D. When I first started out I bought a lot of plants that looked cool at the store because they had them in their aquariums, but none of them turned out to be aquatic. So since then, if I cannot ID the plant myself, I will never buy a plant from a store that does not provide the scientific name for the plant. If you are unsure what a plant is, just get a good quality picture on your phone and create a thread asking about it, someone here is going to know what it is probably. Another option is there is always a ton of people on TPT selling plants, not sure about shipping to Canada, but that may be an option for you, and you may even find a person in Canada that can ship you stuff so there will be no delay in customs.

Mondo grass is more than likely sold at big chain stores in the fish department because they can be used in palladium aquariums. Since its not a true aquatic plant, it can't be submerged. There are some people I have seen online that kept it alive for a very short time but eventually it will melt away.

Might go back there tonight and take some pics. I'm using 2x 13 watt CFL's . 6500k in a 10 gallon is that enough light?

Depending on how the bulbs are mounted, if they are vertical that should put you into the high light range, if they are horizontal that should get you about medium light. There's an awesome post on here about cfl bulbs, I'll go snag it and pull it to here for you.

Follow-Up: Household CF Bulbs, Growing HC, and Non-CO2...

I wanted to follow up to this thread to share some more ideas on lighting with household CF bulbs. AirSong originally had posted asking how much light she should use to light her 2.5gal non-CO2 tank... She was interested in growing HC or other carpeting plants. To her, I answered that she would probably need more than 15 watts. I didn't want to leave it at that however. I set out to investigate and find the right answer. As such, I duplicated her setup: tank size, fixture type, water depth, distance of light from the water, etc... and then took some measurements.

The answer is that you can use anything from 14 watts to 27 watts, and beyond. It all depends on how you set it up...

I personally believe that many hobbyists underestimate the need to accurately quantify their light - especially when they are plagued by unexplained algae or dying plants. The growth in non-CO2 tanks is quite slow and getting feedback takes too long. It's good to know from the start that your lighting is in a good range, so you can eliminate it as a variable if your tank is "less than desirable".

As I discovered, these CF bulbs (14-23 watts) seem fairly tame, but how you use them can mean the difference of not having enough light, and having way too much. And believe it or not, that difference can manifest itself just by moving the light up or down a few inches.

I created a several slides to show what I'm talking about. I hope this will help illustrate how things like reflector type and distance make a big difference, and can't be overlooked - it is also the reason one person's success with a particular bulb may not be your success.

(Hopefully, you've turned off that pesky "image resize" in your user preferences - if not, make sure to unscale for readability. )
