okay, so, i have a 55g tank, put 40 pounds of sand, then added 10 pounds live sand and 40-45 pounds of live rock, 3 weeks ago, did not get my test kit till 2 weeks ago, have tested 3 times since, 0 on everything except nitrates, .5 first, then 0 then 10 last night, have not had any algae growth, except red and purple dots here and there, but thats good right?, have seen 3 hitchhikers so far, 1 starfish, the ones that are uneven and white, several pods, (little white transparent ant things), and 1 either serpent sea star or some kind of worm, cant tell for sure, but there's 4 arms or tentacles coming out of a rock, white with redish pinkish stripes, does this mean my cycle is over, is algae growth a must, what's going on?:confused:
