Ph 7.8 a problem to solve?

[Dr Tomcat]

In my marine reef acquarium (300lt) I have constantly Ph at 7.7-7.8.

Alcalinity and Calcium should be ok. Alcalinity is dKh 12.

Once discovered the PH problem, my acquarist suggested to improve water movement.

Now I have two 1200l/m pumps + one 1000l/m pump from the filter.

Even adding the second movement pump, the PH has remained stable.

Can high alcalinity create problems in rising PH?

SHould I use more movement pumps or an air supplier?

Any more suggestions?

Thanks

Dr Tomcat

Does the PH vary throughout the day?
Are you measuring with a test kit or a meter?
Dies your skimmer need to be cleaned?

If it were me I would simply look for detritus buildup and if none found I would ignore it as a non problem as long as the animals look fine.

Typically low PH is just excess CO2. There's nothing wrong with your Alkalinity as long as your Calcium level is OK and holding steady.
