Dosing Pump

[hfabs]

Dear Fellow Reefers

I keep LPS and soft corals and I have been contemplating to get a dosing pump for the longest time. Can I kindly seek your advice on: -

1) what is the recommended dosing unit that is relatively cheap and reliable?

2) I need to dose calcium, magnesium and trace elements only?

3) If I do a 10% water change on weekly basis (with salt mixed) which I have been doing, do i need to dose on the same day of water change.

4) how often and how much do I need to dose using the dosing pump?

Sorry for the list of queries above but much appreciated if you can provide some guidance re the above.

Best regards

Mark
