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.
