Raising dKH

I need to raise my Carbonate hardness... Its at 7 or125.3 should I just do a water change I don't have a buffer nor do I have a car to go get one.

 

At some point, you're gonna wanna get buffer (and a calcium supplement), but a water change will help a bit if it's a salt with a high-ish dkh.

 

A water change will only work if your salt mixes at a higher dKH than your tank is at. I would definitely suggest getting a buffer or some baking soda at your next trip by a store.

 

I have Kent marine micro invertebrate food? I was planning on doing a water change anyways... I guess i"ll pick up a buffer when I go to the store

 

baking soda? like regular cooking baking soda?

 

Yes, I use it on my tank

 

Well I have baking soda how much should I put in there?

 

Go to Bulk Reef Supply and use their calculator. You will need to know the volume of water in your system. Enter your volume where asked then go to the alkalinity section and enter your current alk level, select dKH from the drop down box, then your preferred level and select recipe 2 and then click on the calculate alk button. It will bring up the answer. You will want to add the number of teaspoons it recommends.
