PH Question

[jordan3548]

So I tested my PH today and I was blown away when it registered at 8.8. Everything is fine in the tank I was just doing some testing, everything else came back normal I dont add anything to it really except for Vitamin C occasionally a calcium buffer Iodine every now and then and thats about it. I do water changes every 2 weeks but heres my readings

Ammo. 0
Nit-0
nitrates-0
Phos-0
PH-8.8
Alk-9
Cal-440

If this is normal or cause for concern please let me know. And if not what do i do to lower it?

do you dose kalk? i'm thinking you should get a new kit or re-cal your meter.

I believe a testing error. What are you testing your PH with?

Are you running a calcium reactor or dosing 2 part? Reactor media or alk part may raise ph as well.
