Calcium in your water?

[efeldmaz]

How do you know how much calcium is in your water??? Is there any way to figure it out. I have a black hannah ph/ppm/eq pen.?
TNX!

 

[whodare]

whatever the ppm of your starting tap water is will be mostly calcium and magnesium...

if you really wanna know start with ro and add calcium to it...

 

[Kcar]

Stick your pen in a glass of your tap water, see what it reads. 70-85% of that is calcium
with 10-20% magnesium.

Some aquarium liquid tests kits will test for water hardness (Calcium) along with other stuff...

• Ammonia
• Nitrite
• Nitrate
• Salinity/Specific Gravity
• pH
• Carbonate Water Hardness
• Alkalinity
• Chlorine and Chloramine
• Copper
• Phosphate
• Dissolved Oxygen
• Iron and Carbon Dioxide
• And others

magnesium sulfate (MgSO4) is the standard. It's also known as epsom's salts.

Call your local water company and ask them to fax/email you the water analysis.

by law they need to have a current report on hand and distribute it upon request to customers.

Why guess?

Cheapest way by far is to contact your water supplier. If you're on a well you can probably get a basic test for cheap/free from a "clean water" or "pure water" supplier that will then try to sell you a $$$ filter. You can ignore this and just use the information they gave you for cheap/free.
