When dealing with marine systems you want bigger filtration to help maintain stability. Most freshwater animals are adapted to wider fluxes of change. I find many canisters to build up lots of waste debris within their mechanics and hoses to bother using them with marine systems. The wider structure of the Rena and Via Aqua canisters are better than the thin 'tubes' of Eheims Eccos and even Fluvals. If dealing with reef...don't bother with a canister and just maybe get or make a sump system. Easier to deal with anyway and the heater can go in it too instead of in the tank. A skimmer can be put on the sump instead of the tank. A refugium can be constructed using a sump. Lots of benefits having a sump system. Worth the extra cost in the long run.
It may seem like a killer deal being only $70, but it may become a useless investment with the particular environment you choose to create and eventually end up costing you more money in the long run.
We, as a people, know so much more about outer space than we do about our own oceans. This lack of knowledge can very well spell the dangers that lay in wait for us.
The oceans surely would swallow us before a rock comes down to smite the planet of it's life.
