Thanks AdAndrews,
It's a tricky dilemma as the more you read the more conflicting reviews you get!!!!
I've read good and bad about both.
As I only bought the tank and lights I have alot of expenditure ahead of me so at this moment in time i'm edging for the fluval 205 unless there's anything more reliable in the same price bracket.
GazGunMan..........I'm trying to persuade the other half to have the tank in the front room Is the 205 noisy?
Yes, I encountered this when planning my tank. At first it seemed like a simple thing but the more you delved into it the more you realized that filters are a big ongoing topic among the hobbyists here, with strong feelings and complicated issues, often clouded by people having different types of tanks and goals. People's opinions of filters are colored by sometimes by chance happenings and by the way they treat equipment.
I don't know the flow rates straight off of the Fluval 205 or the TetraTec EX1200 but my vague recollection would be that these might be apples and oranges, the 1200 being a much bigger (and higher flow rate) filter than the 205. Flow rate is only one of several important comparison factors but its a convenient way to get your bearings when comparing the major brands like Fluval, Rena, TetraTec and Eheim. Flow rate is a separate specification than "size tank that can be handled" by the way (always like to mention that just in case.)
Besides Flow rate and Price, other important factors can be Quietness, Reliability of seal, Pump reliability, simplicity of maintenance, actual media volume, number of media partitions, controls(adjustable shut-offs, flow-rate indicators, maintenance indicators etc.), availability, availability of parts, service, company longevity, wattage, hose adapter simplicity, hose construction, robustness of materials... all sorts of stuff.
Flow rates and other things you may want to know are often buried in the PDFs at the manufacturers sites.
