Co2 you need bigger tank as all of them have said, reason is because the refill for 1kg to 5kg tank is all at the same price. You will be using more as its a 3 ft tank.

Eheim canister filter you need at least 2215 or 2217, there is someone selling 2nd hand 2215 at RM250 here, complete with filter media, http://www.my-mac.net/forum/viewtopic.php?f=6&t=15382, you'll need to register yourself as a member there to view it I think.

ADA soil, I would not recommend you to use Africana, its nutrient deficit as compared to ADA Amazonia. As there is no stock now, you can try other brands like RedSea etc. You can reduce the amount you need by putting in crushed lava rocks at the bottom and more at the back of the tank for a good slope(optional)

The lights you definitely must change, cause they can't grow any plants at all. You can postpone the changing of the Co2 tank now and focus on the filter, lights and soil.

BTW, where do you live? so we can direct you to the nearest and most recommended LFS there.

Osment:
LFS = local fish shop
2217 was rm399 during last promotion. Now not sure if any LFS giving that price
I m looking for 2215 also
Malayan or amazonia is the name given by ADA for their product
Both soil got diff nutrient. Not only will affect your plants but shrimps as well
Try look for other brand for soil. I heard that ADA Malayan is not so good.
Read more article before buying. Don't end up overspend like how you brought co2 tank
If you go ask LFS owner, most of them will tell you whatever soil / co2 tank is good

Its not just the filter, you need to get the filter media also. My advice is just get those cheap bio rings as the filter media, the smaller the bio rings the better.
Amazonia we're talking about is Amazonia II la, if you can get good enough. Don't get the Afrikana or Malayan something.

Go subang NA, its the best    

bro,

use your tank measurement 90 x 45 x 45 then / 1000 = your tank volume

90x45x45 / 1000 = 182.25 Liter for your aquarium... normally the filter rate is 2 or 3 times higher than 182.25 liter will good enough for your tank
so choose filter that filter 546 liter / hour for your tank but for me i would go for 1000 liter/hour

p/s: depends on what plant , fauna and etc you have in your tank =)

regards,
Kenneth
