I've been reading all the great posts in the forum for some time. I've seen so many amazing tanks and learnt a lot from the forum members. I'm no expert in SPS keeping but from my little experience, although it sound trival, stable CA/KH/Mg parameter is very key to the success of SPS keeping.
Some info of my tank: It is about 175G with display tank dimension around 50"x31.5"x25.5". It's equipped with BBK Supermarine 250 skimmer. I'm running modified Balling Lite method with dosing pumps instead of using CA reator. Active carbon in filter socks and zeolite reactor in the sump. The lighting is 400W metal halides with 20K bulbs and 2xVHO. I'm using 2xVortech in short pulse mode for the waterflow.
