So we set up a 20 gallon breeder tank, trying to fallow ADVICE from the web an a chick from petco i know i know . ne ways. We got a coralife purple rock and about 19 pounds of dry rock so 20 pounds all together we were told we could cure our rock in the tank so we built i guess what is the reef? We added a marineland hob filter guessing for fresh water? Been up and running about 2 an half weeks i added a bottle of bio spira per 30 gallon added whole thing were still in the cycle stage only trace amounts of ammonia its already went to its max an back down to trace amounts the niterite is still some where in the low purple from high the nitrate is about a burnt orange. We have added a small power head recomended by aquatic cove.
