i just ordered a salifert mag test kit. but i know my CA varies between 400 - 440 ppm.
as for my lighting, yes i do have PCs.
they are the corallife aqualight 2x96w with lunars.
as u can tell my colt seems good, which that has grown some. my frogspawn (which was sold to my as a hammer) looks more like a frogspawn to me seems to be doing real well also. i dont know what to do, i changed the bulbs not too long ago, thinking maybe the spectrum of the bulbs went kapooty. i really dont think its a water quality issue since u can see the polyps on everything is extended, and i have some nice coralline growth on the glass, and the rocks. the only few things i can think of is the they dont like the lights, they want more, or could be possible since i do not run a fuge or sump? i was looking at the aqualights that have the PCs and HQI MH in them, but they still want $400+ for them. and i am also looking into buy a aquapod nano cube, so thats another $200 some dollars.
another option i may have is going back to using Oceanic salt, right now i buy the ocean water in boxes from *****, which made by catalina. maybe more waterflow? less waterflow? dang, you would think after a year this thing would be booming with corals all over, but i guess i was wrong.
