No, we like people who ask questions first and then go out and do stuff.
I am not familar with that sand brand nor could i find it when i googled it (didnt look too hard though), but if its is similar to this:
Marine Substrates: Ocean Direct Caribbean Live Sand at Foster & Smith Aquatics you are probably fine. You want a sand that will slowly dissolve over time, stabilizing the pH of your system.
And i suspect that the light isnt what you want for saltwater. Look for T5 or metal halide lights if you want to do corals. If you only want to do fish, then that light will probably be fine. Below is a link to a good light, so try and find something similar if you want to do corals. With lights, you tend to get the quality that you payed for.
Current USA Nova Extreme Pro T5HO 10k/460nm Actinics
Also, you want 1-2 lbs per gallon, so i would shoot for around 75 lbs for your tank. You can get dry base rock and just a few pounds of live rock and the base rock will turn "live" in no time.
There is a thread devoted to vendors who sell in Canada, that would be a good place to find corals, fish and equipment. Some local pet stores have good stuff too, just see if their live stock is healthy, tanks clean and the staff is knowledgeable. Also you tank wont be ready for an anemone until at least a year. They can kill everything in your tank if they die, and they are some of the hardest animals to keep in this hobby. They need lots of light and pristine water conditions, which you usually dont have until your tank is around a year old.
Also that skimmer isnt very good. Like lights, what pay is what you get. Reef octopus is a very good brand, and you also want one rate for twice your system size.
Also to mix your water you buy salt and add RODI water. RODI water is very important because tap water (your lake water included) will have things in that can cause lots of problems in your tank like algae overgrowth and if there is copper in it, it will kill any invertebrates that are in your tank. You should get a refractometer so you can measure the specific gravity of your water. If you want to a reef try and keep it around 1.025, but if you have only fish then it is ok to do 1.021.
