High calcium and low alkalinity

[Duncan Tse]

Slacked off on my water testing and here are the current parameters

Cal : 500
Alk : 6.8
Mg : 1500

Calcium feels a bit too high and alk too low. I was planning to stop dosing calcium and just dose alk to bring calcium down to 410 before I add more alk to bring it up to 7dkh

One week later and my calcium is still at 500 and alk 6.8

Anyone have tips to correct my high cal and low alk issue?

Which type of corals do you have? How old is the aquaria?

- Increase your Alk dose accordingly (your consumption might has increased)
- remain interrupting the Ca dose until values are down. After that continue but with a smaller dose

And to help you with this - use the excellent program AquaCalculator that Martin have developed. There is one free version for Microsoft Windows

Okay thanks I have upped my Alk dosage from 15 mL to 20 mL per day.

Will continue monitoring in the next few days and see if my Ca is lowering or not
