Maxima Clam Question

[pinkreef]

Thanks for the reply, my lights are metal halide 250 watt 14000k x2. Also two actinic 92 watts each I think. I run the mh lights for ten hours per day I have tested my calcium and it's at 410 but I am gradually increasing the dose The clam is about five inches by three inches (a chubby one) blue in colour. Hope that helps. Barb
