what do you dose?

[Aquattro]

I dose with a Ca reactor. I refill it twice a year.

Dosing Alk and Calc only. Sodium Bicarbonate and Calcium bulk from BRS. GHL Doser.

[Reefer Rob]

Currently dosing alkalinity and calcium. As my tank matures I'll likely need to dose magnesium as well.

No need to dose trace elements, water changes take care of that. Synthetic sea salts have a much higher concentration of trace elements than NSW. For many of the elements it would likely be beneficial to lower them.

I dose alk at night and Ca during the day. And Mg with a water change every 3 weeks.

[daplatapus]

Dosed BRS alk, Ca and Mg for a year or two. Bought a Ca reactor and never looked back. Like Brad said, refill 2X a year and it keeps my all and Ca rock solid. I still dose a few ml Mg every day.

[pinkreef]

I dose half a cap each of alk mag and calcium at each weekly water change 20g tank and 14g tank

[mseepman]

I dose Alk and Kalk and CA plus prodibio every 15 days. Nice and simple...keeps the nutrients low.
