you need to buy some seachem phosguard or seachem seagel, with water changes ya should be fine, or buy yourself a aplysie kuroda and then bring it back to your LFS or you will need to feed it algae or it ll die

a Sea hare would do. Also, what are your water parameters? Has the tank been running for long? It could be just a "phase" the tank is going through or there are some underlying issues that need to be addressed. Thanks!
I agree, either the tanks not fully cycled or the algae's caused by to many phosphates ie water perameters out or overfeeding,also how long is the tank lit? I'd say approx 10hrs is usual.
