External Canister ot Hang on Filter

[yakie_19]

Hi all, I have just joined this forum after being recommended by a friend who has also recently joined.

I currently have a 60 litre tank, which I just set up 2 days ago, trying to go for the iwagumi look. But I have a question on the type of filter that I should be using, so hope that someone can give some valuable advice on this matter.

I have always been using an Ocean Free hang on filter that seems to work fine for me. But I recently got an eheim external canister 2211. but the water flow seems to be very strong for my tank, causing alot of churing in the water. In the end, I switched back to my hang on filter.

Is there a way to modify the canister to reduce the water flow? I am also considering whether to get the eheim hang on filter 2040 which seems to be easy to use but efficient, and also without the hoses hanging behind my tank. Please advice on this problem.
Thanks

You can install a rainbar for your canister and the flow will not be like a big gush of water coming out.

I prefer canister because it requires very little maintenance. However, I noticed that when I changed the filter in the canister, it seem that the water inside is quite warm. I think this is one setback compared with hang on filter.

My suspicion is the motor and the enclosed manner of the canister somehow warm the water inside. This could cause your tank to have a higher temperature. Good for those keeping fish that like warmer water.

I also prefered canister filter, you have flexibility to direct water flow.

60 liter is about 2ftx1ftx1ft tank, 2211 flow shouldn't be that strong. I'm using 2215 for my 2ft tank.

Anyway you can point the output to the glass wall, that will reduce the flow considerably.

I think you can try get the double tap valve that enables you to control the output of the canister. It also ease you the job of spilling water all over the place when you try to wash the canister.

Here is what you can do:

1.) Add a rainbar to the outlet (water going out into the tank)
2.) Place the rainbar under the surface of the water
3.) Face the rainbar upwards towards the surface of the water
4.) Adjust accordingly till you are happy

Alternatively,
1.) Get a plastic-white splitter
2.) Connect it to the outlet
3.) Split one to the rainbar
4.) Split one to a pipe

I personally suggest splitting up the outlet rather than using one single valve. Please note this is my personal preference and other people have tried other things for them that work just the same.

I assume you are using CO2? then stay away from Hang On filter because you will lose a lot of CO2 due to water surface agitation.

I had this problem myself. What I did was to buy a longer outlet hose. This lets the water travel for a bit before going into the tank and thus a weaker flow is produced.

It is OK, CO2 is cheap, just inject more

I always preferred canister filter. Somehow that water taken in has to pass thru the correct order of filterations system before it returns to the tank. This is something that a hang on filter cant really do. hehe

2211 have more room to put media compare to 2040. Hence, base on different setup can add different type of media too.

I just upgrade from a hang on filter to Hydor Prime 10 (same flow rate as 2211, 300l/h) for my 25cm shrimp tank, can tell the water are clearer and now I can add more shrimps due to the better filtration.

Oh, I just wrap a thin layer of sponge at the outlet to reduce the current, hope it help.

you can shoot the whole tank in, nothing gets retained

guess im the only one supporting HOF, but i've always been a fanaticate with nano tanks, so HOF is by far a more convenient than a canister. The challenge is topping up water on alternate days and ensure minimum surface agitation to ensure better co2 mix.
