Alk is low and can’t do water change

So I have not done a water change in 2 and a half weeks when I usually do it every week. This has caused me alkalinity to drop to 6.5. I’m not sure what to do because I can’t get water to do a water change. all my corals are fine but I am planning on doing a 25 percent water change when I get water. I would love some suggestions on what to do. Thanks
 
Maybe you should dose 2 part for Alk and Cal. What is your Calcium at? How big is the tank? Coral load? If you're able to maintain Alk with just water changes, you shouldn't need much.

I am getting some Kalkwasser to put in my ato soon. My calcium is at 400 and my tank is 20 gallons. I mostly have lps and softy’s only 1 sps.
 
Any reason you can not get water? To mix salt, you can use distilled water from Market Basket
 
If you purchase premix water, test it’s alkalinity before using it.
 
Setting up a nice water mixing station or getting the necessary gear is truly worth it in the long run, makes the hobby so much more enjoyable.
 
A small Sicce will do, Barrel to size of your system. A five gallon bucket might be enough for some!
 
Maxijet 1200 will also work fine in a 5 gallon bucket

MJ is a great pump for this use!
 
If you have baking soda, you can raise the alk to 8. The arm and hammer from Maket Basket will work great.
Here is a calculator for how much to dose
