temp: 80
salinity:1.023
pH: 8.4
Nitrate/Nitrite/NH: all 0
Ca: 540
KH: 6.5

The tank is 75 gallons with a 40 gallon refugium. 75 lbs of live rock and a skimmer. I dose kalk in my makeup water. Lighting is 2x150 10K MH with 2 130 watt actinic bulbs.

Only thing I can see that is off is the KH is low. I am sure that is from the high Ca but my clams and montipora are Ca hogs. I change out 5 gallons of water a week and use RODI water for makeup.

Everything else is doing great. My plating montipora has grown about 3/4 of an inch in the last 5 months and my crocea clam has doubled his size in about the same amount of time...and I can't keep star polyps alive...

They have become my bane. I buy a little piece from the LFS, get it to cover a nice chunk of rock, and then kaput...
