Hi there I just did some testing on my reef system and heres what Ive got.

pH 8.4
Alk 4.0 meq/L

Ca+ 280!!!!

I am trying to avoid water changes right now due to a dino infestation. I trying to see if my fresh water is the source of the problem. I did a major 40% water change about 16 days ago.

1. How did my Ca get so low?
2. How low can it (CA) get before my SPS staart to be affected?
3. How can I raise my Ca without raising my PH+ALK.


I HAVE been adding C balance aver the past few days without raising my CA, why would this be?

What size tank? If it's large C-Balance may not be enough or try dosing more. You have to dose kalk also. What salt?

Turbo calcium and adjust your alk when starts droping with baking soda. watch your ph.
Use this calculator

Proper dosing of calcium chloride raises calcium without affecting pH or Alk.

However, overdosing with any Ca supplement can precipitate calcium carbonate and lower alk.

Sounds good, Can I get Calcium chloride at the LFS?

Its a 55 gallon tank with a few SPS frags......It appears Calcium chloride is the main ingredient in C-balance. What elements are causing the ph to rise?


Ingredients:
Calcium chloride, magnesium chloride, calcium bromide, strontium chloride, lithium chloride, rubidium chloride, nickel chloride, chromium chloride, zinc chloride, copper chloride, cesium chloride, iron chloride, manganese chloride and cobalt chloride.

Which calcium test kit ? Sure its O.K. Maybe verify your results at the LFS before you start changing things. Once you've determine you have the correct results, use the reef chemistry calculator to determine how much product to add. Also check the warnings.

You can get calcium chloride from dow flake (found in some homedeopts or lowes i tihnk, but not in my area) or prestone driveway heat ( yes thats right, the stuff used to melt your driveway in the winter. Got mine at autozone) If you go this route instead of turbocalcium or some other commercial brand you will save a TON. It was only like $8 for 454grams of this stuff or something. good luck

Also the PH is an unrelated issue. I doubt its being caused by that product. 8.4 isnt that bad, just dont let it get too much higher. If you get a chance read Randys article about high PH issues. Its in the reef chemistry forum.

i use Prestone Driveway Heat myself. $9 for 8lbs. cant beat it. i mix 2 cups per 1 gallon of RO water. just like Randy says :D.
