Ph high Alk Low

[Navycook2]

Ok I think now that I have a decent amount of coral that my Alk is being used up fast! I dose my Alk with coral builder by kent! I dose 1 tsp daily. This product also stabilizes Ph but since my coral's are using up the Alk My Ph is at 8.6-8.8 so its on the high level. My Alk is sitting at 3.2 and my Calcium is at 500ppm

Should i just do a small water change?

You can't go wrong with a good ole' water change...you should check your magnesium, because if your mag is off, it'll throw those other parameters off.

First, is your measurement of 3.2 in dkh or meq/l? If its meq... that sounds good.

If its dkh...then you will need to do some adjusting of your water chemistry.
I suggest before you go adding buffer to get your alk from 3.2 to ~9 I recommend getting a second test kit reading. That is quite a large alk adjustment and if your reading was incorrect, will cause major problems.

Try reading this:

The article is not an easy read, but, if you read through it a few times it will help you understand whats really going on. I found it extremely helpful on more than 1 occasion.

You will also need this link to help calculate how much buffer you will need to add:

If you use unbaked baking soda to adjust, it wont raise the PH as much as baked baking soda

And finally, nothing good happens fast. Remember to go slow with additions.
