Need help on PH

[Tony LCW]

Hi Snr,

Need some advise on PH in FOWLR. Have never done anything since day one on the PH level (six month ago)

My current tank is 3x2x2 with sump

I am dosing sugar to lower my nitrate (1 month ago )

I am adding copper to remove ich (2 weeks ago)

However, I need some advise on PH

My current PH reading on a normal day is 8.4 to 8.8

At night is usually higher 8.7 to 8.9

This reading have been all the while not much fluctuation ( more than 6 month)

I suspect the calibration might be out.

I tested on fresh water and it read 7.3

Question 1 : Is above reading Normal or ???

Question 2 : What is ideal PH level for FOWLR?

Question 3 : Do I need to lower my current PH 8.8, and if yes, HOW?

Question 4 : How do calibrate a PH Meter?

Question 5 : Why my PH is not fluctuating. (note: I use coral chip as biomedia )

Thanks You in advance

Appreciate advise or info that can help me on above concern.....thks

You can buy pH calibration fluid at madpetz, aquamarin or local fish accessories store.

At night your pH should be lower and not higher.

Oops ... should be the other way round. I will check and confirm again tonight.

Lights on , = ph up.(algae produce oxygen)

Lights off = ph drop. (Algae produce carbon dioxide)
