Dosing line in the water when return pump turned off

[hllb]

I have an IM 15g AIO tank that I just set up. I dose All for Reef three times daily for this tank (transferred from an IM 10g recently). The water level in this tank is high - when I turn the return pump off, the water level equalizes high enough that the dosing line (and the ATO line for that matter) are underwater. I don't like this, but the lines are at the top of the sump area and I can't really raise them any higher. The water level is still above the bottom of the overflow cutouts. If I remove some of the water, the return chamber is too low. Anything I can do here?

Just cut the tube right under the blue tube holder. Done.

You could do a different dosing tube holder to get them higher and like said above trim the lines up.

Do you have suggestions? I definitely don't like these holders and was going to look for something else.

Is your return pump adjustable? If you reduce the flow rate of the return pump it will reduce the height of the water in the display and cause the water in the back chambers to not go as high when the pump turns off, once extra water is removed or evaporates off.

It is, but already at the lowest setting. It's a Mighty Jet 326.
