Check out my levels....i have a question

[drock59]

So i just tested my tank today and here is what i came up with.

pH-8
Temp-79
Calcium-450
Mag- 1470
Alk-9.9
P04-not detectable
nit-?
amo-?

My tank has been progressing nicely but i have been having some pH issues. Just wondering if the pH could have something to do with my high Calc or Mag? Anything harmful about having levels of Calc and Mag so high? I have been aerating my water with fresh air for three days and pH has not budged.

Overall the tank is doing great, i just get a little concerned when the pH drops below 8.0.

My tank hardly ever makes it to 8 on a PH test. Usually I'm around 7.8-7.9. I wouldn't be to worried about your ph being 8 as long as it wasn't 8.4 a couple of hours ago. If it is stable with a small swing I believe that is normal and just fine. The problems with ph are when it gets real low or when it has a large swing in a 24 hr period. If it is swinging around .3 in a days time I say you have nothing to worry about. Thats my opinion and others will/may say differently.

I take it that below 7.8 is not good.

I hover around that all the time and I believe my tank is doing well. It could be better but all is growing and show good color. I have never had my ph above 8.1 and never below 7.7/7.8. Like I say Dan its just my $.02.

Well it is nice and comforting to hear someone else in this same boat. My pH has never been above 8.1 and generally sticks right around 7.9. Ill just go with it, everything seems to be doing really well.

Yeah my SPS tank is the same way, my pH peaks at 8.11 and the lowest it ever gets is 7.82 and everything is growing really good.

As for your mag and Cal is looks like a good level to me.
