I can't keep it up

[ewelch]

.....My PH that is . I know I know , another PH question .

My PH hovers around 7.8 , highest I have ever seen it is 7.9 . I have tried opening windows , skimmer air intake outside , co2 scrubber on input . Nothing seems to help .

Temp :77
Alk: 8.6-8.9
Calcium :440
SG:35

I am measuring PH with a Milwaukee PH controller . Calibrated to 4.0 and 7.0

Any suggestions ? Should I even worry about it ?

Calibrate with 7.0 and 10.0

It could be better but I wouldn't chase it.
How do the corals look?

Take a glass of tank water and measure pH. Move the water to outside of the house and aerate it for 20 minutes then measure pH again. Tell us what you find.

This is something I constantly hear when talking about pH.

Use kalkwasser in top off. Watch alkalinity and corals and don't worry about 7.8 ph

What? No pHiagra jokes?

It's possible. Family has been in South Carolina since the 1600s. Before then who knows... trail goes cold. Most likely England. Oh, it's pronounced HAZEL-den, a lot of people try and say HASSEL-den.

Calibrate with 7.0 and 10.0

I will order some 10.0 solution

Corals look okay , i have lost some test SPS but i attribute that to a young tank and fluctuating parameters

I did this , no noticeable change in pH

I have very little coral demand right now . Even when i run very small amounts of kalk in my ATO it pushes the Alk up .

Just keep up what you doing.
Your tank is young and still finding it balance.

Given your Alk level and that outside air aeration did not raise pH, I'm thinking it is pH probe bias which will clear up once you calibrate with pH 10 and 7 buffers.

I would also suggest re-calibrate with 7 and 10 solutions.

Welcome to my world and the world of many others Read Randy's article on pH. before anything else.....Consider running higher Alk as it has helped me although it takes more additive to maintain. I run 3.7 meq/l which is about 10 Dkh I think.... and with a scrubber I hold pH at about 8.0 at the absolute best....as soon as the Sodalime starts to go mauve it drops to 7.9 but I very rationally refuse to replace it for a little while after that on cost grounds. Running Alk a little higher could help you...see Randy's graphs .

What time of the day are you testing it. If the lights have been off all night it will be lower in the morning than say in the evening. Mine fluctuates from 7.8 to 8.15 daily and my corals are all fine.

What time of the day are you testing it? If you are testing in the morning when the lights have been off all night it will be lower than say in the evening. Mine fluctuates between 7.8 to 8.15 every day and my corals are great.

He has the Milwaukee Ph controller. It gives a digital Ph reading constantly. They're frigin awesome! I have the monitor version that just reads, but the controller has sockets for dosing when out of range.
