Lightbulb SKimmer & Filter

I have a question. I am new to the saltwater world. Do I need both a skimmer and a filter, or can i use one or the other? I haven't set up a tank yet, but I am planning to. I plan on doing at most a 30 gallom tank. but most likely I will end up with a 10 gallon. (my wallet would hurt too much on anything larger).

Welcome aboard. Are you ready for this answer.... it is kind of funny...

The skimmer is the filter. Read this short article:

Does this mean that a filter (0.25 u) can be s skimmer?

Are you saying a 25 u filter will not remove the organic matter that a skimmer removes?

Now if you follow that 25u filter with a biological canister...done.


I ask since I was recommended a Ocean Clear canister filtration system:

Ocean Clear 325 for the mechanical removal of organics, etc. followed by a Ocean Clear 318 Biological canister.

Ocean Clear:

Mechanical Filtration
- is the physical removal of particulate matter from the
water.This is achieved by introducing a mechanical barrier in the water flow
that traps particles of a certain size according to the filter material used. A
mechanical filter is only effective when it is cleaned regularly, otherwise bacteria
will settle in and start breaking down the collected dirt, thus setting minerals
free into the water as well as becoming a bio-filter resulting in increased nitrate
levels.
Biological Filtration


- is the process by which aerobic (nitrifying) bacteria of
the genus Nitrosomonas and Nitrobacter oxidize the toxic ammonia through
nitrite, (which is only slightly less toxic than ammonia) to the relatively harmless
nitrate. This process is known as nitrification, and in nature takes place in aquatic
habitats and soils where ammonia and sufficient oxygen are present.
The nitrifying bacteria develop naturally in an aquatic environment and will
colonize any suitable filter media such as the Polystrand filter pads supplied in
the Ocean Clear Filters. Once a biological filter media has been established it
should be disturbed as little as possible since the bacteria colony maintains its
level of activity according to the bio-load present in the system.

So, will this not work as well as a skimmer?

I will say this is for a fish only tank so some higher levels of nitrate are allowable.

So, if we want to "REMOVE" the organic waste to keep the nitrates lower then the skimmer will do that job better. Is that correct?

Is there a closed system skimmer that would fit in my above filter system to lower nitrates IF I wish to have that in the future?

This is a 300g SW tank with dual/independent filtration lines as described above.

why not do it with a skimmer, deep sand bed, sump, refugium (w/ a macro algae like chaeto) , enough live rock, flow, properly stocking/feeding, patience, water changes to replenish trace elements and you'll have 0 nitrates. you can also run carbon and phosban reactors, uv sterilizers... but i personally wouldnt waiste money on something that i can do other things to get better results IMO. with any kind of filter, even filter socks they need constant cleaning.

The setup will be in an area that requires "quiet", and therefore, I have opted for a closed system with offsite pumps. The overflow method will cause water flow noise and evaporation, and therefore is not wanted. This setup will not have live rock but will be a saltwater fish tank. UV are on each leg of the filtration system.

Nitrate can be controlled with a denitrator working on a 50g container of aquarium water and used to refill with near zero nitrate water.
