Thank you NoFishing and Adrienne for your replies.
Adrienne,the main reason on why I want to go to a canister filter is that,I have trouble keeping water clarity.
I have always seemed to have white little bits floating around in it,my ideal water would be crystal clear,yet I can not seem to obtain that.
How ever on saying that,there is the possibility that I have had too much filter media in my trays.
This is how I have had them in each tray bottom up,ceramic noodles,two or three layers of micro pad,the coarse black sponge and a layer of filter wool under the spray bar. I think this may be causing by pass of any muck collected.
This is how today I have changed it,bottom up,ceramic noodles,one layer of micro pad,black coarse sponge and a thin layer of like a fine wool mat under the spray bar.How ever in the last tray(out let end) I have noodles,then two bags on Macropore (about 700ml total) then the coarse sponge with the fine wool mat on top.
I have noticed a difference by changing it that way,I have swimming pool filter sand as the substrate.I also have a flat black back ground,which at times I think high lights any light colored particles in the water.
I will admit I am probably overstocked a bit,11 Rummy Nose Tetras,4 Neon Tetras,5 bronze Corydoras,3 Pepper Corydroas,2 Bristle Nose and 16 very small Rosy Barbs,the Barbs are in there as the previous owner was going to dispose of them,so I took them off him.I do intend to pass at least 10 of these barbs off to another person.
The tank has rocks and plant wise,java moss,java fern and anubias,so it is not overly planted.
When I have taken the actual complete filter body off to clean,I have noticed like fine granules in the bottom. I thought that it could be the noodles breaking down or just sand picked up by the intake tube.
As I said since reducing the amount of media the water does look better,maybe I am striving to much to get that crystal clear look.
Sorry about the long winded post,I would be very interested to hear what you think and any advice you could give.
However, prior to barbs I was still having the particles in the water.
If I could avoid putting in a canister that would beneficial to me. I thought maybe adding one would help.
Foot note: I have the 980T,water capacity 240ltrs.
Thank you.
