Dosing reef tank

[reefhobby]

My calcium in my 45gallon cube reef tank stays about 400 for calcium I wanna bring my calcium up to 430-440 for better coral growth. Any suggestion how to raise it and what calcium to use

I am just getting started with my tank, but there are a lot of dosing options. I am using Bionic, but i hear nothing but good things from the 2part at Bulk reef supply, and ME corals i think is the name of the company.

BRS supplements and 2 BRS 1.1mL dosing pumps, need a digital lamp timer to set auto dosing times. Works like a charm.

You really need to measure SG, Alk, Cal and Mag. That being said ESV, BRS or ME supplements can be used.

What test kit are you using and what are the levels of the water being used for water changes? After a water change, where are your levels at?

I'm using Red Sea ans the level is 400 and its stayed about 380-400

What type of Red Sea (Sea Salt or Coral Pro?? And what SG are you mixing to?
See recommended from Red Sea site for Coral Pro Salt

Its possible you have a batch low on Cal. My last container of RS Coral Pro was low on Alk. I would set desired alk before my water changes and that would take care of everything.

If you are just boosting calcium, the thing to use for that is calcium chloride. Almost any brand is equally fine.
