Yesterday was water testing and water change day. Did another 5 gallon water change and changed filter socks.

Params are
Salinity: 1.026
Temp: 78
pH: 8.0
Ammonia: 0
Nitrite: 0
Nitrate: 10
Phosphate: 0.120
Alkalinity: 9.7
Calcium: 405 or 450 depending on test kit
Magnesium: 1380

Does anyone have a good recommendation for calcium and nitrate test kits? I have Hanna and salifert for calcium and they have a huge diffet in test results. And my nitrate API reagent is low so I will need a new test kit for that.

I also did a dip in coral revive for a few of the struggling corals. Hopefully that will help them a bit.

My large frogspawn is looking worse today. All closed up. With water parameters seemingly ok, could it be the lights or too much/too little flow?
