  • Can there be too much water flow in a reef tank?

  • Water flow and movement is crucial for the health of your reef tank and all of the fish inside, but is it possible for there to be too much of a good thing? The answer is yes: If the water flow is too strong in a particular area, coral will avoid growing in that spot.

  • How much water does a coral reef tank need?

  • For soft corals and LPS corals aim for at least 20 times turn over, and for SPS corals, at least 50 times tank volume turnover per hour. So for a 250 litre reef tank, it needs a minimum flow of 5000lph and for SPS corals it would need 12500lph.

  • How important is water flow to a reef?

  • Water flow isn鈥檛 the only important factor in keeping a healthy reef. It鈥檚 also important to keep a close eye on the water鈥檚 pH, alkalinity, nitrate, ammonia, calcium, and phosphate. A saltwater tank鈥檚 pH should be between 8.2 and 8.4, and most saltwater mixes are formulated to start your tank off right.

  • How often should water turnover rate be in a reef tank?

  • Saltwater tanks should have a water turnover rate of six to ten times per hour. You may be wondering why water movement in a reef tank is important anyway, and there are a few different reasons for this.
