Good evening
Just tested the system, it been since October 19th
I am going to adjust the salinity and the Ca should come up a tad bit and alk will drop a tad bit.
Phosphates are sky high, time to dose Lanthanum to drop the phosphate. It should take about 1.5 weeks of dosing every 3 days. I am going to bring the phosphates down to about a .02 and let the algae die off. Next balance the nitrates and phosphates.
The new gyres are doing wonders with water movement. The old gyres were barely moving the water compared to the new gyres. With the water movement and balancing the nutrients my system hopefully gets back to normal.
There are two things that I can think of that killed off the tank.
1. one the exterminator spraying from out side, but they swear that they use natural pesticides and it will not affect the tank.
2. The county has been spraying for mosquitoes at night. That might be the issue.
Since I vent the skimmer to the outside, the pesticides might be suck in to the skimmer and then the system. I add carbon in the line to filer the air from outside. This has been an on going problem since April 2017. I have tried everything and lost a beautiful coral scape. This is all that I can think of.
I am going to test tomorrow to make sure my number and compare today number the the new number tomorrow.
After cleaning the glass with a Magic Eraser to get the hard stuff off, the glass to pretty clean.
