Sump and Filling

[Ashv5]

Hello!

I am almost ready to fill up my system. First time using a sump and working with overflows. I just wanted some advice on how I should fill up the tank, when I should turn on the return pump etc. Also, I have attached some pictures. Pls check if my set up seems to be ok (return nozzle has been fitted)

I was also wondering how loud the sump system is going to be. I am using an eheim return pump.

You should go ahead and clean the tank while you can unless this is just a leak test.

I would start by pouring a gallon or less of water into the overflow box where those pipes are. This will let you ensure your bulkheads are not leaking. Put a towel under in the stand below the bulkheads that will let you see if you get any drips and catch them.

If there is no drips and the plumbing is ready, I would go ahead and fill the display tank to just below the inlet vents at the top of the overflow. Then fill the sump to the desired water line level and turn on the return pump. You will need to add several more gallons to make up for the volume in the pipes and overflow boxes. Draw a little line on the sump where you set the water level in the return chamber and top off the tank with RODI water every day to maintain that water level. The water level will only be changing in the return section of your sump where the pump is located so it will be your indicator of how much top-off water you need.

Regarding the noise, the main culprit is going to be your overflow plumbing. What you have is called a durso-tube style overflow. These are fairly noisy compared to options that require more plumbing lines such as a Herbie or Bean-Animal style overflow. They are not terrible though, the durso tube is designed to keep air in the drain so that it cannot siphon easily which would create a loud flushing sound followed by loud gurgles. The durso is more a constant steady white noise and less irritating. A herbie or bean animal can be made totally silent though so if that is a necessity they may be worth exploring.

Eheim makes great pumps, putting a small rubber pad under it and using flexible tubing on the return pump can eliminate most vibrations which is the main noise you will notice from a return pump.

Awesome thank you!
