Hi All,
Wondering if I could get some input as to what is going on.
My tank is about 2 months old. 90 gal with 25gal sump. I have about 7-8 SPS pieces in my tank. Also one frogspawn. Over the past month, I've had great coloring up and polyp extension. Today, all the corals only opened to about 35% during the light on period. My frogspawn which opens to the size of a softball every day now is the size of a baseball.
Parameters last month:
Salinity: 1.025
Temp: 74.5
PH: 8.1
Ca: 450
Alk: 8
Mg: 1100
Salt mix is Red Sea Coral Pro salt. It mixes to those levels, which is way different than what the bucket states. Test kits are Elos.
Current parameters:
Salinity: 1.025
Temp: 74.5
PH: 8.1
Ca: 400
Alk: 8
Mg: 1000
I've been dosing a little mg to try to increase it but it's been marginal.
Any ideas what's going on? Or is this just something that corals do?
