it just channels the water from you tank to the sump they are very handy and reliable to have.

i think if i put my tubing/PVC just below the waterline like im talkin like 2cm i dont think i will have a proablem with m sump over filling and im goin to put a valve on so when i turn the pumps ove the water is being siphond in to the sump. like i said i wanna tr and keep this simple

There are people out there that make there own overflows to save $. You need some kind of way to get water from DT to sump and most people like to use an overflow so they can get water from the top portion of DT for skimmage

There are basically two possible tank setups. The first tank does not have a small tank that contains its equipment and such, so all the equipment to filter the tank must be contained in the display. This type of tank is referred to as being "not drilled" because it doesn't have holes drilled into the bottom for water to travel to the sump. The second kind is a drilled tank that does have holes drilled in the bottom and an overflow. An overflow is a rectangular box that is 6" wide and 6" deep and as tall as the tank. The overflow is in the tank and has slits in the top of the overflow to allow water to flow over the top. The water that flows over the top of the overflow is then piped back to the sump, where it will be returned to the display by a pump. If you were to shut the pump that is in the sump off the water would stop going to the display and the water would not overflow into the overflow. Hopefully this is making some sense.

The main advantage in a drilled tank is that the equipment can be located in the tank below the display and out of sight. The sump also allows for an in-sump skimmer to be used which tend to be much better than HOB skimmers.

i cant use a pump and have the return PVC just above the water to put the surface scum back in to the water

Kyle, the biggest problem with turning a tank that isn't drilled into a tank with a sump is in the overflow. A drilled tank's overflow is going to allow water to return to the sump using gravity, while a undrilled tank is going to have to return water to the sump by siphon. Now, if the siphon is broken for any reason, then you a pump in the sump that is returning water to the display, but the water that is going to the display is not being returned to the sump. Within a minute the tank is going to overflow and the water in the sump will be put into the display. There are ways that a siphon can be restored automatically if broken, but that usually means more money.

you could do something that looks like this
