How do you lower the alkalinity??

[carey1465]

My alkalinity in my tank is around 16. What's going to be the safest way to lower it? I read online the best way is to let it go down by itself. I have some water mixing now just in case I need to do a water change.

The best way to lower it is slowly. Small water changes would be okay. SPS are sensitive to large swings in Alk.

+1 do small daily or eveey other day water changes.

Tropic Marin makes a product to reduce alk.

Virtually every time someone has something out of whack here, it turns out to be a bad test kit What kind of test kit are you using?

Well I had my banner fish and my Pakistani butterfly die within the last few days. I checked the water parameters and everything was good except the alkalinity. I tested it with the api test kit. Like I said, it was 16!!!! I hate the api test kits but its the only kh test I have.

Do yourself a huge favor and throw that API kit in the garbage.

You can buy a SeaChem, Elos, Hach, etc., or just go to your LFS and ask them to test your water.

Good reliable testing is a 'core' requirement to being in this hobby.

'Cheap reef equipment' is an oxymoron.
