Just throwing it out....

If I was you, I would put a chemi pure bag, a carbon bag and a handful of chaeto and put a small led clip light over it...should be an overkill filtration (according to me ofcourse)

api for nitrate should be all you really need.....in a tank that size, it's doubtful that you will have enough coral in it to deplete Ca, Mg and DKH to the point that you will need to dose between W/Cs.....if you want to test for those tho, then go with either elos or salifert, by far the best kits available to hobbyists

Thank you very much. What would be a good stock list for this tank. I was thinking just some sexy shrimp porcelain crab maybe a pompom crab and a fish.. but what Linda fiah can be happy in such a small tank.

According to a post in nano-reef, the following can be your possibility (but limited to just one I guess):

-Blue Neon Goby
-Catalina Goby [cold water]
-Clown Gobies
-Eviota Gobies
-Panda (Clown) Goby
-Redhead Goby
-Trimma Goby
-Yellow Neon Goby
-Citron Goby
-Green Banded Goby

BTW where will you be getting a pompom in Calgary? I would love to get one too :D

I work at a lps and can order them in so if i can get miine i can get one for yyou but its pay up front though. I work at the petland in shawnesay and we order marine from little fish but only as special orders. I will have my pin pin porclian and sexys by next wednesday

Oh cool :D

How much would it cost? I am actually thinking of getting a pompom crab (mayb a couple if the price is fair for my wallet :P) and a maxi mini anemone. I think you can keep those in a 2.5g too. Any clue how much those might cost? You can PM if you don't like to put the price over here :D

My levels on my fish tank on day one are

Ph- 8.0-8.2
No3- 20-30ppm
No2- 0
Nh3- 0

What is the best way to get my nitrate down?? Ideas!

Simple: regular water change :D

So the tank is well my Ph seems to be kind of erratic cause i tested this morning and its sitting at about 7.8-8.0 a little low so Im kind of concerned lol. Also with my tank When should I be doing water changes, I was always a once a week kinda guy but inorder to get my levels down should i be changing it every few days about 5-10% or more??

Since you have like 20-30ppm and you should want it between 0-10ppm (I am assuming you are using API), so I think you can do like 10-20% water change in every couple of days till you get your desired level and then can move to weekly.
