Diff between salt and fresh filters?

Question:

Thanks for your time!

Answers:

in some cases chemistry is used in place of a filter, for example i am dosing vodka in my tank, the carbon from the vodka binds on a molecular lever with No3 (nitrate) and Po4 (phosphates) making a new compound, turning it into dissolved organic that is either feed on by bacteria or skimmed out with my protein skimmer,

As for the salt water being more acidic.. no. Marine tanks are often more alkaline than fresh water. However, salt water can be a bit hard on working bits in a filter. One of the main reasons salt water filters are more powerful than fresh water is to maintain the quality of the enviornment. Salt water fish and corals are more sensitive (and more expensive usually) than fresh water. Live rock really helps here as it does a lot of the work of a filter. If you have live rock, standard filtration is enough in most cases.

the difference is that in salt water the water is mostly acidic and heavy so the filters used for marine aquariums are very much powerful then the fresh water aquarium and there are different types of filters used in the aquarium like protein skimmer and like calcium rock filtration etc marine aquarium is hard to maintain but when its running in good condition it will run good but if some thing happens its very hard to maintain

I never used filters mainly because I had live rock. but I would just fill the filter part with live rock chunks or those cylinder pumice looking things. Its all about the beneficial bacteria.
