is this pH too high?

[mmarine9]

pH hit 8.61 tonight. I run a scrubber and dose kalk. Dont see anything wrong with corals but just wondering if I should maybe turn off the skimmer or something or if its ok.

This is a little high as although it drops at night, you want a ceiling of 8.4 opposed to what you have currently
As ALK can control Ph- check your alk numbers

all is 8.3

8.3 very acceptable

I would calibrate pH probe.

I would calibrate pH probe.

bought profilux second hand , less than year old and calibrated when i received last month.

Turning off the skimmer will allow pH to rise further, if those values are accurate and alk is below about 12 dKH.

In general , pH is never too high, no matter what a pH meter reads, in an aerated reef tank not using high pH additives.

I expect pH 8.6 is not accurate, but it is OK if it is.

sounds good and yea I dose about 400ml of kalk a day , run fuge at night, co2 scrubber, have a exhaust fan bringing fresh air in to the room the tank is in. so i definitely do a lot of things to try to raise ph haha.

Probably should have mentioned that when asking about the pH. lol

I did mention the kalk and scrubber in original post

Definitely high!

Sorry, missed that.

He's at 8.3 and recommended range is 8.0-8.4. No way is that high. My tank is at 8.2 -8.3. As Randy Holmes stated, if steady at 8.6- not high in a sense.

 

[mmarine9]

yea i dont think 8.3 alk is high at all haha my nano runs at 11dkh.. 8.6 ph seems high to me though idk what caused it to go from the normal 8.5 peak to 8.61 now i might start dosing less kalk and more all for reef.

If this was happening in my reef I'd be comfortable with that range. I'd also recalibrate the probe again to make sure it hasn't gone off in the last month since you received it.
