On March 20th I tested and nitrates were 0ppm
230 gal dt
I dosed 1ml per 20 gal as instructions
11.5ml daily for 4 days which should give me 4ppm
Testing today results show I only have 2.5ppm
But alk is extremely high at 9.0dkh
sg 1.025
Cal 425
Nitrates 2.5
Phosphates ( March 20) 0.159ppm ( 52ppb phosphorus )
question …
Does dosing calcium nitrate effect alkalinity ?
Or is it the sudden decrease and increase with dosing that’s messing with alkalinity ?
