Increasing calcium level?

[zkx1325]

Hi all,

the current status of my tank...

kH: 10-12

pH: 8.3 - 8.4

but the calcium level is only about 250-280.

is the healthy level about 400?

how do i increase the calcium level?

thanks for helping!

Well you could try adding those powdered or liquid calcium solutions or maybe try dosing kalkwasser but you got to be careful as it is around pH 12.

Another way, if you are going to grow SPS or other calcium depleting organisms, you can invest in a calcium reactor which will save you a lot of trouble once you get it tuned.

Hope this helps

Hi,

i think partial water change might be better.

.....my 2 cents.

Your pH is already quite high... must be very careful if you are to try dosing Kalkwasser... if you really want to give it a try... dose in small amount at night as the pH tends to be slightly lower at night (no photosynthesis).

As suggested by bro BH, you can also dose powder/liquid calcium... but they can be expensive (esp. if you have a large tank). Do follow the recommended dosage as overdose will affect other elements creating ionic imbalance.

Do check your Magnesium level too as it will affect Calcium too.

Another method is through water change... using salt mix with high Calcium and Magnesium. I've tested Marine Environment saltmix a couple of time and it offers optimum level of Ca and Mg... perfect for your situation.

Do consider a CR for the long term... your Ca level is critically low... stop introducing new corals... in fact... you might even wanna consider selling off some of your stony corals to lighten the consumption rate (for the time being).

All the best!
