Help How To Bring My Alk Down??

So I been trying to bring down my alk. Right now is at 11 something. (I'm still asleep) lol My cal is at 500. My ph is steady at 8.34. My mag is around 1100. I know its low, but I dont want to does if its going to raise my alk. I've been doing 20% water changes every weekend for the past month. What else should I do?

I have a cal reactor. The co2 is off at the moment till the alk comes down. I was using bright well mag. I stop that also. So right now, I'm not using anything.

You'll only get it down through water changes, as mentioned increase the volume of them.

Correction - alk is acceptable at 7-8, so you are on the high side.

Does your test kit measure Ca past 500 (some don't)

What is your PH?

Nothing is wrong with the Alk being at 11 - that is within acceptable range.

So it could be even higher than 500
Keep up with the water changes then.

I've heard that some batches of certain salts (like reef crystals, red sea coral pro, and Coralife were recently testing at high alk levels (like 14 or higher in some cases) so be careful. I'd test a batch of fresh saltwater before doing a water change.

Oceanic salt test out at about 540 ppm for calcium, that and your reactor is bringing your levels over NSW levels. I bet that you were compensating on your reactor to bring the alkalinty up due to Oceanic having a low alkalinity.
Just keep your reactor off and do nothing except for your maintenance water changes.
11 DKH is not harmful. Some European hobbyist keeps their alkalinity in the 12 to 13 DKH range, I keep my alkalinity at about 11 DKH also and there are no burnt SPS tips. Your levels will eventually come down from coral intake, corraline growth and if you change out the salt brand.
