So, I did a round of testing today. 10 days since last testing. A minor concern that levels are falling.
I did a water change last night so that may be why...
Current testing shows:
No3 2-5.. barely detectable on Salifert kit. I will run a test on the Hannah tonight.
Ph 8.3
Po4 0.03 again, barely detectable on the Salifert kit.
Mg 1260.. This seems low to me especially after a water change?
Kh/Alk 7.3-7.7 I am just between the marks on the syringe on this one.
Ca 400. Again, seems low for day after water change.
The phosphates, magnesium, and calcium all seem pretty low to me. Nothing dangerous, but definitely something to be aware of and monitor.
The nitrates could be attributed to the refugium doing its job. I usually only feed once per day. With the old tank, I never saw nitrates this low, but I also did not have a refugium to pull them out.
I first filled the tank on 7-10. Reintroduced the rocks and livestock in the early morning of 7-12.
Basically, it has been running with stock for 26 days.
Honestly, even though this is an upgrade, I realistically have to look at it as a new build with a skip-cycle. With triple the volume and more than double the footprint, plus the addition of the sump and refugium, a new build is really what it is.
