Filter or wet dry

[jbamboo]

Hello to everyone, Hobbist of Discus

I'm new to the group... and i will enjoy your opinion about to breed Discus

I live in Davie , Florida

I think to have Discus only for hobby not breeding

I think to have a 125 gallons tank.

My question is :

It's better 2 canister filter Magnum 350 gallons per hour or a wet dry 150 Essphos . ?

my other question is : that is the wet dry is better.... i need a 125 gallons tank with overflow or a plain 125 gallons tank ??

thank you so much for your help
