Are this perimeter OK?

[AlexG818]

I have a Red Sea reefer 250G2+ 65g total water volume. I have mostly SPS corals. Here is pic of the numbers. Also have a refugium.

I think there are some typos? Salinity of 25 then 34?

Are you dosing calcium?

What are the nitrite units of measure?

My bad it’s 35

NUM is PPM. Here is what I dose

You sure you mean you had nitrite at 15 ppm?

 

[Randy Holmes-Farley Verified Community Expert]

I’m not understanding how calcium can bounce around like that. I expect there’s substantial test error involved.

What are you testing with?

I had a spike of nitrate not sure why. Lost a coral.

I wonder that as well.

Your chart shows a spike of Nitrite (NO2) to 15ppm not Nitrate(NO3)
I would not even bother with testing Nitrite after your tank is established assuming it is since you said mostly SPS corals.

Not a good video but tank is established. I stated dosing in September before that I had no issues

Could it be that I’m adding coral ?

@AlexG818 Tank looks good.

At this point I think you need to take a closer look at your testing practice, products, etc. Something seems off with the numbers as compared to how your tank looks, and a lot of bouncing around with the test results.

I just ordered sever testing kits.

Calcium I check it with imagitarium master reef test kit

Calcium I check it with imagitarium master reef test kit

I would recommend Hanna for nitrate, phosphate, alk. Salifert for Calcium.

I'm on Randy's bandwagon for not testing mag.

Imagitarium test kits get very mixed reviews.

I got those and I was recommended Red Sea test kits as well

Redsea test kits are fine too, don't really need duplicates. Their calcium test kit is apparently quite good.

That’s what I have heard as well. But don’t know anyone that is using it. Do you know anything about the Hanna all in one kit?

 

[Kooma]

Is your alk actually moving that much in a day, and phosphates 1.5 to 0.2 in a day?

That will kill corals very quickly.

OK
Would not expect an established system to have a Nitrite spike as I said above I would not even test Nitrite then.
