yes a water change will bring it down, but there is really no reason too if you PH is normal you are fine er well should be fine. what is your ALK level? or do you have a kit that just reads "low/med/high".
I use the Red Sea and it only shows low,med,hign and it reads high.
yeah that's what I had. But if you do a water change it should bring it down. Normally I would tell you not to worry about it , but you don't have and true reading. So I would do a normal water change.
I'd also get a decent test kit like SeaChem or Salifert...something that gives you a meq/L reading.
I'm pretty sure someone tested with a redsea and it said 'high', but a seachem test gave them a reading of 3.0meq/l which isn't high at all
