There is some good info on this topic here;

my mag is now 1500 and i have been using epsom salt for about 10 days. I have now added cal everyday and don't get a change. so yesterday i added about 3 tablespoons of turbo calcium to get a big increase but i tested it after and no change. i know this is more involving cal than mag but i just need help. I need 450 cal levels.

 

HL14,

What is your Alk reading? Also, be a bit careful trying to get an instant Calc boost. Snow storms are very messy indeed

my alk is at 4 meg/L

 

Sorry HL14,

I also meant to ask what the current Calcium levels are and why you think that you need 450ppm, my apologies.

John

 

my current cal levels are at 320 and they go up. I want about 425-450 cal levels.

 

HL14,

Have a look at this link, fill in the boxes as it may give you the info you are looking for

Also, how often are you doing water changes and how much water?

John

 

it says i have to add 86 grams of my turbo cal. It says below that i can add 1/2 now then the other half in a couple of days. I haven't done a water change in 3 weeks. i was doing like 10 and 15 gal. to get rid of some phosphates.

 

Well HL14, Sounds reasonable to me

Unless you see a need to change water, then don't do any changes until you get the calcium level up. Doing water changes will only complicate the issue in the short term IMHO

ok i now tested my cal and it's at 390. i've added like 4 tablespoons everyday for the last 2 days.
