Hi,

Here is how I have set up a few large systems, one is 700 gallons and the other is 300 gallons. Both systems have dosing pumps and I use one of the pump heads to dose small amounts multiple times per day into the sump. In the 700 gallon system the Foz Down is dosed into one of the 7" filter socks in the sump. The 300 gallon system is just dosed directly into the sump. I use the 8oz bottle of Foz Down with a rigid plastic pipe that connects to the inlet side of the dosing pump.

Another option is if you run an ATO system is to add some Foz Down into the water container. If you dose kalk with your ATO then I would not mix the kalk with the Foz Down.

For my 800 gallon system I manually dose into the sump. I am presently in process on setting up multiple 7" filter socks so once they are in place I will dose into those.

I am more than happy to offer suggestions for your specific setup if you like.

Cheers,
Tim
