Starting a new Tank - advice requested

[Red Fish Blue Fish]

Sump Canister filters (IMO) are not very efficient for saltwater. A good wet/dry or sump is better and cheaper in the long run. Canisters have a slow flow rate and calcium deposits destroy the impellers as they are not really made for saltwater or they would make a salt and freshwater canister. For saltwater you would need better seals. Again just my opinion

Clearly everyone wants the OP to go sump however, i'm pretty sure OP has set their mind on a canister

Having said that, I do have some friends who use canisters and they seem to like their Eheims. I myself used to have one, a 2217 that was rock solid and lasted like 6 years until I sold it. What I really like about my Eheim was the fact that it had huge support. Everywhere I went someone sold Eheim parts for it.
