O.k. heres the story...I have a 30 gal tank up for about 4 weeks. When I first started I was told to cycle with fish, so I went to the lfs and pick up the essentials to start....first off i had only the advice of my father who had a tank running about 7 years ago and has since given it up....anyway picked up salt,live sand and a few base rocks(nothing Live). Already had the tank the skilter and 1 powerhead(ajustable flow). Now the bag of sand said INSTANT CYCLING. Did not really now about cycling till I starting looking it up(on the Net)after i had put the 4 damsels in. My parameters were fine so I THOUGHT the bag of sand had cycle the tank(very funny).Well after thinking my tank was cycled I purchased more fish....2 tomato clown, 2 neon gobys,and 1 striped dotty backplus a small cleang crew....well 1 damsel has died 2 pep shrimps, all of my 20some snails and now my clown are looking poor..note my damsel died firstfrom bullying from the other damsels. Anyway the real cycle started as soon as i was expecting the other fish in the mail(fedx). Now my parameters are through the roof(amm And NItrite) and have been like that for almost a week and a half...have used stress zzyme and biozyme to try to kick the cycle in the a@@. Dunno what to do. It seems never ending. Can i use ammo lock to try to save some fish.Bottle says it still bio filters the amm. Please help me..............reminder im very new at this and the advice I was taking was a joke.........thanks Chris H.
