Recently my water parameters have been out of balance

nitrate: 50ppm
pH: 7.8
Alk: 6.5dkh

any help on how to lower nitrates and increase ph and alkalinity would be greatly appreciated
I test nitrate with salifert and ph and alk with red sea, any tips on reading the results more accurately would also be appreciated (I can just never settle on what the reading is with slight colour differrences)

Surface aggitation increases pH. In order to amp up it further up you can add some baking soda (not baking powder). This will also increase your Alk. To lower nitrates, either use something which filters nitrates, consumes nitrates (bacteria for example) or water changes. A water change will also help oujt with the other parameters.

Thanks,
I was actually working on surface agitation earlier today and tried to attatch the "duckbill" return pump nozzle instead of the random flow generator since that creates for agitation but the manufacturer of my return pump didn't ship the thread to attach it to the pipe so I am searching for that

Check the alkalinity of the water you’re using for water changes. If it’s lower than it’s supposed to be you may find your salinity is low. How are you measuring salinity?

salinity is at 1.025 and using a refractometer to measure
I will check for salinity of the new saltwater and then compare to tank water

Alk in new saltwater is 8dkh
alk drops significantly when I test tank water

Surface agitation may either raise or lower pH, and may have different effects at different times of the day.

Ignore pH for now. Boost alk with sodium carbonate. There are lots of different suitable ways to lower nitrate.

BRS calculator comes up with this, if you choose to use bicarbonate of soda to raise alkalinity, best to check it out for yourself though; Assuming tank is still 85 liters and you want it raised to your fresh saltwater alkalinity;

No problem :) Are you calibrating your refractometer with RODI water?
I calibrate it after use with RODI, I have heard things about that you should use correct calibration solution but my refractometer came with RODI water for calibration and no 1.025 calibration solution, is this right?

what is the best way to get a stable ph

Stable pH or higher pH?

Higher pH can be obtained many ways, such as fresher air to the room, high pH alk supplements, growing macroalgae, or aeration with low CO2 air (outside air, CO2 scrubber, etc).

Which refractometer?
