SPS Corals

SPS corals (small polyp stony), also called Scleractinia have a hard skeleton. SPS corals are least tolerant to nitrates and phosphates, which must constantly be close to zero, and also extremely intolerant of warmer water temperatures. SPS Corals need an almost perfect environment to maximize the potential for their vivid colors. If you can’t provide ideal conditions SPS corals will rapidly perish.
