corner filters and sumps

[Chris4Reef]

i dont use these filteration methods and for a 180-220 gallon aquarium i believe that it would be easier than 4-5 canister filters.

So i have looked at a few models of tanks and they have those internal filter boxes in them. im assuming that the water enters through the top and falls into the box. then im assuming that a power head pumps the water out of the tank and down into the sump where it is cleaned and then pumped back into the aquarium.

or am i missing this concept.

i really dont want to drill this tank so im wondering if it can be used like this.

Yes, this is VERY viable concept!

I have made tanks with these partitioned sections and filled them with live rock crumbles and oolite sand (the sand would need to be in a nylon bag to prevent the pump from picking up the sand)

There are pre-made versions of these (such as the ReSun BF200), but they are generally used in smaller tanks, although 4 of these would work for a 200 gallon tank along with some opposing power heads.

just keep in mind....if i`m envisioning this sump correctly....alot of water is lost by evaporation

I think BC is referring to back internal wet dry filters, such as found in Bio Cubes, some custom tanks, and the ReSun Bio Filters I noted earlier (with a link).

These types of bio filters do not have as high an evaporation rate as traditional wet dry sump styles filters.
