You can reset and focus at least 6 months on good husbandry before trying out sps. Reason being you need a stable tank to keep sps. The 6 months please avoid buying fishes, just keep a few herbivores small fishes to tackle algae problem which is quite common during the first 6 months cycling period. IMO for sps, stable water parameters is number 1, any big fluctuations to your kH, Ph, temperature or phosphate level can cause your sps to stn or rtn. A dosing pump or CR is a good investment. Weekly water change and a good Skimmer will help in nutrients exporting. Second on the list would be flow, you need good random water flow. Will be a challenge if your tank is shallow and have a sandbed. 3rd on my list are lights, too strong a light can bleached your sps, too low a light will most likely result in brown sps.
Because sps are sensitive creatures, its worth while to invest in reliable equipment, stick to reputable brands like eheim, arctica, tunze or vortech.....etc
