Help, I have a 55 gallon tank with a sump, protein skimmer, I bought off of CL
the live rock was included. I scrubbed the rock but I didn't get all the alge off. My tank is beautiful everything is looking good except I had my phosphates tested at the fish store. The phosphates tested at 1.70. I was told I should get a reactor. I took the sock out of the sump and did a 15 gallon water change. I starred up the water with a turkey baster while siphoning out the water. Today (next day) I tested phosphates and it is still high. I don't have a lot of fish, don't over feed, one time a day and I only give a little bit of food at a time to make sure all food gets eaten. What should I do???
