Canister filter or sump?

[nickmcmechan]

can you do your water change out of a sump?

 

[fastforward]

Sure, if you're so inclined. I have sand substrate in my 125 so I do my water changes out of the display tank so I can vacuum, but lots of people do their water changes out of the sump.

 

[nickmcmechan]

just thinking a sump would be great for example on a discus setup

you could gravel vac oncer per week and do the other water changes out of the sump without disturbing the tank

I have a sump that returns to the main discus tank driving a RUGF.

And is a sump alot better than a canister or just a bit?

 

[Rbishop]

I feel they are a lot better, but for most folks, a canister adequately fills all their needs.

I have large tanks, like to overstock, and can have some plants in the sump that would get destroyed in the main tank.

Well if i have the money i will get one of these, how big does a sump need to be for a 130gal?

 

[Rbishop]

ANy size will be beneficial, for my 125s I have 55s as the sumps. They probably actually operate with about 40 gals in them.

25% of the tank volume is the desirable minimum with 33% being the preferred volume.

Please note that the fabrication of the sump with respect to the flow paths and filtration processes is critical to the appropriate functioning of the sump.

I got a pre molded plastic sump witch can handle a 6ft for $250 australian much cheaper than an eqiverlant canister.
