Abstract

To better understand effects of macroalgae on water quality in reefs, Ulva sp. a genus of fast-growing macroalgae commonly associated with coral reefs worldwide was grown in a lab in conditions typical of coral reefs for five days. Calcium, magnesium, alkalinity, phosphate, and nitrate were measured in the experimental tank containing Ulva sp. as well as the control tank that did not contain Ulva sp. twice per day (before grow lights came on and before the lights went off) on days one, three, and five. Given limited tank and grow light availability, replication was achieved by repeating the experiment four times. Tanks were drained, cleaned, and refilled between replicates. Ulva wet weight was measured at the beginning and end of each replicate experiment.
