Reefez kalk and calcium plus

[FuEl]

I have noticed that Reefez kalkwasser comprises 98% of calcium hydroxide with a small percentage of calcium carbonate.

Reefez Calcium plus..comprises mainly of calcium chloride, magnesium chloride..and strontium (ahaha..finally got the spelling right) chloride.

So my question is....do we need to dose these 2 products together? Will dosing calcium plus alone have any effect on the ionic balance of our marine water since there are chloride ions involved?

I feel like changing to calcium plus..but I'm still unsure if I should.

kalkwasser = maintain calcium

Calcium plus = raise calcium level

wat i think is that if ur calcium level is below normal level then u use Ca plus to raise it up... normal topping up of water shld be done with kalkwasser to maintain that level...

Kalkwasser provides alkalinity and calcium in a balanced 1:1 ratio, so your ionic balance wont get out of whack. disadvantage is that the amount of calcium supplied is usually not enough to raise (or perhaps even maintain calcium levels) in a moderately calcium-consuming tank.

Calcium chloride will raise your calcium levels very fast and efficiently. The problem is that with the rapidly raised calcium levels, your alkalinity levels will take a dive. So to add the two in a balanced ratio and to maintain the correct ratio, you also need to add a buffer (carbonates and bicarbonates) product like Seachem Reef buffer to raise the alkalinity levels too.

Ah ok..thanks for the clarification.

But actually I'm more concerned with the excess chloride ions being added into the water. Will they pose any problems?

I dont think so.

The 2-part balanced additives (such as ESV, and Kent) is basically calcium chloride (Part A) and bicarbonate salts (Part .

They get rave reviews in the US, so should not be a problem.

manage to come by this thread so was wondering, what is the amount of each and buffer to add?

Measure your current alk and cal levels.

Dose accordingly to raise it up to your desired levels.

There is a limit to how much you can dose in a day or you'll cause stress to your corals/cause calcium precipitation/cause water ionic imbalance eg. your alk or ph could drop.
