hi there,
my numbers work it out at being 81 litres. Therefore, if you use the 10x rating, you'll be looking at AT LEAST 810lph pumping capacity, so i think the 205 might be a litlle small. i've got both fluval and eheim filters (all bought second hand) and i'm really happy with them both. I guess my advice would be to go for the biggest filter (in terms of flow rate) that you can afford! Also i'd suggest using a spraybar instead of a lily pipe. I don't have co2 (yet!) but i've noticed the flow distribution with a spray bar is very even and, if set up right, gives a much better flow to carpeting plants (even in smaller tanks) - see this topic

Good luck buying! I got my filters through both eBay and Aquarist Classifieds - give 'em both a try if you don't mind second hand!
Cheers
