I randomly testing the calc and alk in my tank with no reason. Everything is doing great in the tank.

PH 8.35
CALC 360
ALK 400+ way off the charts!

What do I do to get the alk down to even the 200's? I tested twice and it took 20+ drops to turn the test tube yellow. What is going on?!?!

Are you dosing anything?

I was dosing reef code parts a&b a week or so ago but havn't put anything in for a while. How would the alk get so high?

Try another test kit. I don't even think you would be able to see into your tank if the alk was that high.

It does seem abnormally high. I too would check it with another brand kit.

That said, the calcium should be brought up with calcium chloride, or just the calcium part of the two part. :)

It's crystal clear... something have to be off.
