Alkalinity help please

[elcapitan1993]

So I’m confused and need some help I have a mixed reef tank softies/lps and I have been testing my alkalinity each day for 7 days to try and figure out how much to dose each day, I am using the Hanna alkalinity checker so it’s pretty accurate, my problem is it’s staying the same I have no drop in alkalinity from day to day and it doesn’t make sense, every time I test it it reads 162 or 162 ppm, I have plenty of lps in my tank so it doesn’t make sense can anyone tell me what’s going on?

Check weekly.
Your consumption isnt needed for daily testing. Add an sps.

So it’s not unusual for this to happen?

How bigs your tank? Got a fts? How much lps or purple coralline? Might be normal yes. Watch calcium too. The two are tied together. Ur mag will be the last to drop. Keep watchin.

As pointed out check the Big 3 to ensure you're balanced enough for consumption to be trackable
LPS in my experience use far less Alk than SPS

It’s a 90 gallon tank with a 20 gallon sump 60 pounds of rocks, not coralline, my calcium is at 420 according to api and 495 according to salifert test kit, I am waiting for a different test kit on the mail for calcium, my magnesium is 1310.

It’s just weird because I was having to add in 15ml of alkalinity a day then I added some corals lps and softies now it’s not dropping at all, I have been testing everything every day because it’s worrying me but I don’t want to keep testing so much

Just slow ur dose or amount a little and keep watchin. Good job. Bump your mag to 1400-1450 if u can.
Small wc will balance parameters if mixed correct or u can dose the wc water to help bump. Hths looks great.

Judging by your picture you have virtually nothing coral-wise to consume much Alk.
Your previous dosing need was most likely bacteria consuming it. Now that your tank is settling in your seeing the true use by your corals.

Two of my previous 75g tanks both used around 100-120mls of 2-part per day.
When you get some skeletal growth you'll see your Alk start to change.

I never thought about it like that but that makes sense, thank you.
