PH swing

[strykerdog11]

Hey guys Iv been experiencing these rather large PH swings for awhile now well over a year. Any tips on how to lessen the swing? Alk is about 9.7 dosing all for reef 20 gallon tank about 11.7ml per day. Would upping all to 11dkh help? Thank!

This looks photoperiod related; down at night, up during the day!

More aeration will reduce the swing, and perfect aeration would eliminate it, although that’s not necessary.

Sounds good ill try increasing angle of flow to cause more surface agitation! Thanks for the tip!

You won’t stop the PH swing with just aeration in a nano. Ask me how I know haha.
