Hang on Fliter VS Cannister Filter

Hi all,

What's the difference between the 2?

I am using Jebo 838, but it does seems to be "sucking" those dirty stuff in.

Feels that my old hang on filter is better.

Can tell me what is the difference between the 2?

canister create less surface water movement, reduce co2 loss also usually have bigger filter area for beneficial bacteria to colonize

Isn't that a filter supposed to do?

Anway how big is your tank? HOF is good when you are using a small tank ( it is great for nano low tech reef tank) As for CO2 escaping the water column due to water surface aggitation by HOF, it is better to go for internal or external if you do not have CO2 injection, else it should be fine. My 1 feet low tech tank has an internal eden 104 filter, which works great with only bio media and no filter wool.

A tank of 2x1.5x1.5 has a 100% volumne of 127liters, and around 102 liters at 80%. We usually take the 80% range as the tank contains gravel/rocks and basically mass of water displaced by what we put in.

The ideal flow of the filter is said to be 3x-5x of what your tank volume is, but if you can go higher as better flow rate is better. However don't compromise your plants and its inhabitants (fishes find difficulty swimming, plants swaying too much). Just try to hit a maximum flow rate where the fishes and plants are ok with.

For the two taps, open the inlet from the tank to the filter to max. Do not adjust the inlet. Only adjust using the outlet, that is the point where the filter returns water back to your tank.

Imho a 2 footer 600 l/ hr is good enough.

sorry double post, how to delete?
