I just ordered a fluval 305 with intentions to put it on my 10 gallon planted tank, but I know that it is rated for a 70 gallon tank and has 260 GPH.

maybe I will just swap my eheim, ECCO 2234 and it is rated to 60 gallons and 145 gph, from my 30 gallon...

I question the "rated" numbers for my eheim, I know that its flow isn't very strong, but it should be enough for a planted 10 right?

minimum stocking, 1 Red marble BN and 4 cobra guppies. I am getting ready to bump that number to 10 guppies soon.

eventually both canisters will end up on my 75 gallon that I am still piecing together.

Also the reason for the canister is so I can use my DIY reactor for the CO2, rather than just buying a diffuser.
 
I don't think the flow will be a problem I've run filters rated for 50-70g on 10g planted before w/o issue.
 
I'd keep an eye on the guppies. They don't seem to be the most agile or strong of swimmers, so if it looks like they're struggling, I'd recommend either adding holes to the spray bar, or DIY a longer spray bar with more holes to diffuse the strength of current.

Ok thanks authmal.

Certain plants can look pretty crappy in a high flow situation , even if their actual health isn't affected. Imagine a stand of Vallisneria or other plants with long grassy leaves having the leaves being held permanently in a horizontal position by the flow. On the other hand, certain plants such as Bolbitis and Fontinalis will be healthier in high flow situation.
