how do i lower my alkalinity?

[Michael]

you say your alk is 23 dkh, out of interest whats your ph?

+1.
If those indeed are your Calcium and Alkalinity measurements, your pH is probably extremely low. If your pH goes up to fast, you will have a massive calcium precipitation event. A water change with new water at a higher pH could cause that to happen. If your livestock isn't dying, I'd unplug the reactor and not mess with the tank for a few days and let all the parameters fall slowly back into line on their own.

And go to a store for a second opinion on those tests. I can tell you from experience that sloppy testing procedures for Calcium and Alkalinity (i.e. not adding one drop at a time and mixing between each one) can give you some very strange results.

To follow up with everyone first thank you guys so much for helping me out. The all was extremley due to the co2 from the reactor. To many bubbles I had someone mainting my tank so I didn't question it. But I fired him cause he was totally unreliable and his customer service was the worst! So I took charge determained to learn seen all was to high listen to you guys stop using the reactor for a week no water change and next thing you know Par were back to normal alk 11 dkh cal 420 ph 8.2 mag 1200 nitrates 0 phos 0 everything is perfect. So turned on my reactor again once parm were good lowered the bubble count and for the last 3 to 4 days everything has stayed perfect. I guess like people say know one will take care of your stuff like your self. Thanks again for everyones input you guys helped me keep everything and now everything is just fully opened everything looks great.

Doing water changes everyday? You have to account for the alk of the source water. In our case it mixes way higher than we want to run our alk so we does muriatic acid to lower the alk before water changes..

Wow. You woke up an 8 year old thread. What salt are you using? Have you tested newly mixed saltwater? Ca at 350 is bad and alk is not way off either. That's not causing your issues with BTA.

What does my cal need to be?and as far as salt i use instant and i ocean crystals

Other than the anemone, what else is growing in your tank? If you aren't growing any hard corals, keep your kH at around 10 and Ca around 350-400. If you are keeping stony corals, then we need to know a bit more about what you have and the rest of your setup.

me too!!!

me too!!!

I am having the same problem...my brand new saltwater in the mixing
tank is alkalinity of 12 !! Same thing in my reef....why is it so high?

I never had alk this high until the last year...my alk was always around 8.

What the hell is going on? Is it the Reef Crystals salt I am using or is the RO water>?

Should I test the RO water itself and if so what should the alk of it be?

Thx
Tim

why do you even have a calcium reactor for???? you don't have many corals....

Hello. A year later..
Ok. My alk is measuring T 300KH by the test strip (6 n 1) things. I know I know... I'm getting a real test kit today.
My Calc 400. That's a drop in 1 week from 430. Mg is consistent at 1410. Ph is about 8 (that real test I'm getting today. NO3 10. And Phos 0.
I'm new to having a nano (32gal bio coralife) and am finding I really need to keep on top of things as opposed to my 300gal softie beloved tank (RIP) that had tons of forgiveness.
So I've tried to find a conversion for the alkalinity and can't. Help! Do I need to panic? I'm running RO to do a water change in case...
My biocube has been running for about 6 months or so.

Thanks!! Lisa
