In any case, your alkalinity is within a safe and healthy target. Higher alkalinity can lead to faster growth rates in calcifying corals, which is a benefit. :)


If you want to go down a rabbit hole, you can make a DIY alkalinity standard that will work for any titration kit:



A standard can help you know exactly what endpoint color you must strive for. Let’s say the standard is 7dKh. You can use the safest kit to reach 7dKH, and then you’ll know the correct endpoint.

I think I’d add a drop or two more. Looks too gray for my preference.

I highly recommend the Red Sea Alkalinity Pro test kit for the future. It’s very reliable. That’s what I use.

Thanks for the help. I don’t necessarily want total accuracy, i just want it to be consistent. I’m still curious as to why it would jump. I’ll test tomorrow and see if it is the same. If it is, I’ll just leave it.

When I do that it shows around 10 dkh. I’ll try the red sea one next time i run out

I’d trust the salifert test kit for now. Your alk is within target, and total accuracy isn’t important. I keep my alk around 10dKH with thriving corals and clams.

If you want the alk lower, just stop the dose and let it trend down. Your tank doesn’t seem to have a high demand in the moment.

Good luck. :)

I also forgot to mention im in the process of switching to red sea blue bucket from a pre mixed salt which is another reason that the alk could be different, although it still doesn’t explain why it would jump so much higher. I’ll just try to maintain the new alk if possible. Anyways, thanks for the help everyone
