alpha cone 170 or 200

[foreverfortune]

thanks guys for the response. i was only considering the 200 because it wasnt too much more(110usd), but from what i have read and the reponse from here the 200 might be a bit overkill for my system.

i read some reviews and ppl were suggesting the 170 for 125g and below, i just might go
for that!
i was gonna get it from a usa site (there are a few). that list the 170 at 699usd and the 200 at 809.99usd with free shippiing to a usa address, but shipping to a canadian address would cost about 70usd.(unless i got it shipped to a usa address and went to pick it up)
i just may buy from jlaquatics for about 150can more and save myself the duty, troubles and headache.
thanks for the responses.
