I am also in the process of cycling my first tank. Its a 120dis w/ 55gal sump. I began cycle 9 days ago after placing my dry rock aqua scape in the dis and more in the fuge (approx. 120lbs total)… dropping in a shrimp and began seeding with auqavitro seed. My skimmer (rsk 300) went crazy for the first two days just overflowing with liquid foam. I spent quite a bit of time with the ATO off, letting the skimmer waste drain into a bucket, and topping off with fresh saltwater (also raised my skimmer elevation so water level was right at the bubble diffuser, about 3 inches) My local fish store guy said the excess skimming was prob from the auqauvitro Bond I used for the aqua scape. After the 2nd day, skimming became manageable at the raised elevation so I let it run it coarse for the next 5 days. As of 2 days ago, shrimp is gone (it was marble size), ammonia - nitrite - nitrates all tested zero and water is still very close to crystal clear. I shut the skimmer down, added another larger piece of shrimp along with a bottle of Dr. Tims one and only. Today, ammonia tested about .1ppm and still zero for nitrite/nitrate but water is a little cloudy. Am I on the right track?? first time cycling a tank and am very anxious of the process...Just want to make sure I am going about it properly and what I need to look for. Any advice/insight would be greatly appreciated! Thanks all!!
