Dosing question ???

[Madimod]

If you are using a doser where do you put your tubing in your sump ? Do you put it in the return section or in you skimmer section ?

Return chamber.

Make sure the ends of the tubes are above the high water level even with the return pump off.

Why have the tubes above the water level?

Good to know

I suspect he means so if the water level raises it doesn't uncontrollably add a few mL's of each when the water creeps up. mine are low because the Neptune magnetic probe holder/dosing line holder I use is designed for use with both and obviously requires it to be low so the probes are half submerged so I'm even more puzzled. at any rate, it's never been a problem for me so I'm also curious if that's the reasoning behind it.

as for OP's question... I keep them in the return as you want them to dose and enter the tank quickly to avoid the doses contacting each other and precipitating but if they're staggered far enough apart I don't think it'd be an issue in your skimmer chamber.

Often you’ll get precipitation of the dosed solutions if lines are spashed or submerged. Depends on what’s dosed and the concentration, but it’s best to keep the tubes out of the water.
