Alkalinity help!!

[Joel Franco]

I'm wondering if the bottles are miss labeled, you think your adding ca but it's dkh

I dont believe so. That would mean that for the past 2 years of using the product it would of been messing up my parameters.

I was more getting at this current batch could have been boogered up but you answered that already.

The odd thing is that I added about 6 new zoa frags into the tank within the past 2 weeks and they are growing heads really fast and have not receded like zoas do due to bad water parameters.

I'm kind of in the same boat. My alk was climbing and ca was dropping. So I was only dosing ca. I stopped dosing the ca for a bit and the alk stopped rising, but wasn't lowering either; It actually remained the same, and continues to remain the same as my ca is being consumed..... following

I have a Deep Blue 80 gallon tank that has been up since the 24th of December.
Temp: 78 degrees - Apex
PH: 7.93 - Apex
Calcium: 435 ppm - Salifert
Alk: 8.9dkh- Salifert
No3: 10ppm - Salifert
Po4: 0.1ppm - Salifert
Mag:1460 ppm - Red Sea Pro
Salinity: 1.026
What could be causing ALK to increase?

Just noticed that the tank has only been up for a few weeks. Alkalinity rises from declining nitrate and drops from accumulating nitrate. Did you have higher nitrate levels first? Nitrate levels that are falling would cause this to occur.

Calcium cannot be consumed if alkalinity is not. There is no mechanism for real calcium consumption without alkalinity consumption.

The explanation for that lies elsewhere, such as water changes with a mix not matching the tank, alk being added without your knowing it, rapid reduction in nitrate levels (which adds alkalintiy), or testing error.

OP, I am in the same boat. I also switched from Aquaforest to Fritz a couple of months ago and I've had the problem of rising alk as well. I have not dosed anything in the past two months.

The Fritz mixes to about 7.7 before I use it. My alk last reading was 10.4. A week before this it was 9.6. No water changes since 1/18.

I have a ph badge and it says my ph is low I added a air stone what is the best way to raise PH
