Ph always remain low

[sheristopher]

Hi All,

My 2ft tank's Ph always remain 7.6 even after I had dosed seachem PH buffer for 1 week.

What should I do next?

Can I leave as it is?

what equipment u used to measure PH? with light or light off

Assuming there is no die-off in your tank.

Check your water flow and air exchange.

Besides decomposition, low flow and low air exchange will depressed pH.

Try to do test before and after photo-period to get better results.

get a PH pen then those unreliable test kit

I feel solution base test kit is more accurate than ph pen .ph pen need to calibrate over time to ensure its accuracy.

Measurement of NH3, high ammonia leading to ammonium can cause ph to drop. If tank is cycled, NH3, NO2, NO3 are 0/0/low, then check kh. Carbonate hardness affects the ph swing. If ur kh Is low, then ph can swing alot. Marine tank i read shld be 8-11kh.

having more fresh air around the tank will help.

Fresh DI/RO water wil help too...LOL!

My pH tends to run low, around 7.9. My research says don't worry about it. Calcium, alkalinity and magnesium are more important to watch.
