Ok this is the situation
My system consists of
- temporary DT of 151Gl Total water volume
- Sump of 187Gl total water volume and about 150Lbs of life rock
- Fuge/ Seahorse display of 105Gl
which makes the complete system a 443Gl system.
I use fresh Ocean water which comes out of the gulf of Thailand which is checked by myself and has all parameters sitting at ideal sea water levels. (as per most websites stated as ideal sea water levels that is.)
now the problem.
Due to some missed water changes I faced some Nitrate/Phosphate issues. Low issues though but issues nonetheless. Anyway those have been dealt with and are recovering slowly due to new water changes and some phosphate lowering treatments.
Anyway as my levels of Magnesium and Calcium were very low due to the missed water changes they still havent recovered since?
They currently sit at
Ca 420
DkH 6.1
Alk Meq/L 2.16
Mg 1170
my Ph swings from 7.92 at night to 8.09 midday
Salinity 1.025
Temp 77.3 - 78.6
How to deal with this?
- I was thinking dosing baking Soda to raise my Ph which would bring my Alkalinity back to normal?
- dose magnesium?
- Just continue with large water changes and sit it out?
any advice would be highly appreciated here
Thanks
