It is better to leave two pipes; in case one gets clogged, the other will continue to drain the water. In such an overflow situation, it is advisable to calculate the free space in the aquarium so that it can hold all the water from the return compartment.

And how is this to be read?

Multiply the length by the width and height of the return chamber; if the dimensions are in decimeters, the volume will be in liters. You also need to add the volume of water that will drain from the sump into the return chamber because the water usually stands 1-2 cm above the partition. Then take the length of the aquarium, multiply it by the width and the height from the edge of the comb to the top of the aquarium minus 1-2 cm, and then compare the two resulting volumes. If the aquarium cannot hold all this water, you need to reduce the amount of water that the pump can draw from the return chamber, for example, by simply raising the pump on a stand.

The pump will be adjustable. From 2700 to 4000 liters per hour. And what is this calculation for? Is it in case of a power outage when the water starts to rise, if I understood correctly?

This calculation is for the case when the drain gets clogged or, for example, air gets trapped, and the water from the aquarium stops draining. When the power goes out, the sump should be able to hold all the water that will drain from the aquarium without overflowing. To reduce the amount of water that drains back when the power is off, a siphon should be installed.

Well, that's what I meant, I just explained it incorrectly. Phew, what a hassle with this overflow. Basically, what could cause it to clog or get airlocked? There's a comb at the inlet that won't let coarse particles through. And the compressor will constantly blow out air. Just in case, I'll connect the compressor to the uninterruptible power supply.

a comb with a comb, but I recommend installing a coarse sponge, there is no noise and the fish won't jump out, we gave up on the combs.

It's easier to initially calculate the volume of water that the aquarium and sump can hold and feel at ease. I have an acquaintance who didn't calculate the volume that the sump could hold and submerged the return pipe while he was at work. When the power was turned off, about 500 liters of saltwater leaked out. The aquarium weighed a ton and was located on the 17th floor of a new building, but fortunately, on the 16th floor, there was a suspended ceiling, and the owners accepted the water.

I simply cut a PVC cover for my pocket (I have a drain organized through it) to protect against fish and snails.

The air from the overflow column is pumped out not by a compressor but by a pump. Or are you really planning to connect a compressor? So, you don't need to connect the pump to the power supply because even if the column gets airlocked when the electricity is turned off (which is unlikely), it won't cause any harm. When the electricity is turned back on, the pump will remove the airlock, and the overflow will work. But connecting the compressor to the power supply is just right!

Do you see the transparent hose up there? It is used to capture air. If there is a missing overflow somewhere, it can become airlocked. The compressor will be there to prevent this from happening.

Do you have a compressor to which a suction hose can be connected so that it can suck air? Even if you do, after it pumps out all the air, it will turn into a pump and start pumping water, which is salty and conducts electricity well. If the membrane breaks, the compressor will short-circuit with unpleasant consequences.
Jade
You are mistaken; this tube is not for continuous air suction and certainly not for pumping. It is meant to start the overflow by removing air and raising the water level to the overflow level. This is done very rarely. This is an old-fashioned method!
Eric
Do not confuse the sinful with the righteous, that is, the compressor with the pump.

Guys, I've said everything, and what I said has been tested for at least a year in practice. If a person has money, let them buy brands and not complicate things. If they don't have the cash, they should roll up their sleeves and build a simple setup without overcomplicating life. They can save up to buy a Tunze or start a new aquarium, and everything will be different. Why add anything or complicate things? It's all clear. My brain is starting to boil trying to explain what this is, and it's just rectangular, not a cinder block or a brick. Good luck.
Patricia
You are right. A compressor is needed for the start. There is even a video about this on YouTube. And there is a misunderstanding about what can cause air entrapment. Could it be from an uncontrolled water level?
Chad
Send a link to a video showing how a similar overflow is started with a pump. Airation will occur because you have a very wide overflow, which means there will be a low flow rate, and the bubbles that enter the overflow will remain there. This is regarding the overflow itself. On the other side, there are two Durso pipes, which can become air-locked if all the water is drained, for example, due to a clogged grid on the return pump that reduces its flow rate. It will take some time for them to restart. Why don't you want to drill the aquarium and make a standpipe?
Leonard
There is no link. But it's called CS Overflow-Overview and Installation. Look for it on YouTube. I thought about the mine, but I don't have the skill to drill glass, and the mine takes up more space, and there are nuances with the mine as far as I know.
