Calcuim

[reefguy352]

Just testd my Calcuim and its at 350 i want it at 420 i have red see reed foundation abc how much of A do i need to add and over what amount of time

Nitrates - 0
Phos - 0
KH - 8


My MG keeps testing over 1600 i tested it twice just to make sure and im using red sea test kits so i know its accurate if done right.

so bsically how do i get my mg down and my ca up i have never dosed before so this will be my first time any advice would be great!

also i do weekly water changes and mix with red sea coral pro

There are instructions in the box and on the bottle. Should give you dosing instructions.

First you need to decide what method you will use to handle the ABC elements. Besides water changes, the practical choices for most is either adding Kalk (provides alkalinity & calcium together in a single powder & mixed in RODI water) or doing 2 part dosing (2 different products that can control alkalinity & cLxium levels separately).

You'll start dosing by hand, then you may want to automate it.

First, get comfortable using your test kit and record your results. You'll spot trends on how much you use over time; this is critical to know. The magnesium level will drop with usage, no worries there. It sounds daunting at first but you'll find it to be rather straight forward once your research.

Describe your tank & you'll get better feedback. How old, how big, RODI, what kind of corals, etc.

its about 3 months old 55g with a few LPS frags (hammer brancher gsp galaxia) i use rodi water that i make myself it is hooked up to a ppm reader as well so its good water

Adding Ca to raise the level isn't a big deal. Here is a link to a chemistry calculator. Plug in a few numbers, tell what brand of Ca you are using and it will tell you how much to add and how to add it.

Ron that website is exactly what I needed! you're the best

Except it doesn't list RS Reef Foundation.

another post listed the formulas for converting from the products on the chemistry calculator to the rs reef foundation

What salt do you use? How often do you do water changes and how much? You usually shouldn't need to dose Calcium with just a few lps frags in a 55g tank. Maybe switch to a reef salt with higher Ca levels and save yourself the headaches of dosing?

Actually in a closed water system with live rock you have tons of other organisms extracting calcium out of the water, coralline algae, tube worms, soft corals (contrary to belief) use up CaCo3.
