well i usually purchase NSW from LFS.
From the last time reading taken till yesterday, I only changed 10% of the water. So changes will be minimum definitely.
I bought mixed salt water from SL the last time. Have not tested their water param yet.
On the Mg level, I have underdosed the Mg. Suppose to dose 20ml daily to raise it Mg by 18.5 ppm per day. I have been dosing like 5 ml per 2 - 3 days recently.
I will dose 20 ml of Mg daily for 2 weeks and see how's the response.
Nitrate remains because a couple of fishes died due to the rescaping, my skimmer was not working for the last 3 days.
I have yet to install my Eheim Cannister 2026, with the biohommes and more carbon, it should drop to about 5 ppm
Lets see how things go 1 week later.
