Sorry for the length in advance, just want to provide whole story.
10 gallon Tank;
nitrite 0;
nitrate 0, Harndess 0-25 (color on strip between 2),
chlorine 0,
pH 6.8,
ammonia .5 (now, was 0 see story below for details); temp 76
I bought a ten gallon tank, set it up on dec. 27, filled it with bottled water and left it run for 3 days. Tested the water and all the numbers above were the same except for the ammonia was 0. I went PETSMART and purchased 4 fish (based on the advice of employee there). I like the way the tiger barb looked, the emplyee said I need to get at least three so they school, so I got three. I also wanted a fish to help clean up any extra food, so he recommended and I liked the rainbow shark. Brought them home and released them into the tank. All seamed fine for a while except for the larger of the Barbs (female) who died 6 hours later. One of the barbs seems very aggressive towards all of them and he banged in to this one alot, the other one was too fast. The water has become a little cloudy. Took it back, got two more barbs, thinking another one could calm down the nipper. Well put the new ones in, the next day one of the original ones is swimming upside done and dies later that day, and one of the new ones looks sick (sitting still at top, not eating). I did like a 10%
water change. Now learning about (more appreciating it) I figured that the leaving my tank running for a couple of days at the beggining was really not doing anything but pushing water around. So I went out and bought Nutrafin cycle and added it to the water. The sick Barb mentioned above was dead the next morning, and to add insult to injury, the shark jumped out of the tank and is now dead (Only small gap in hood next to filter, an amazing jump). This morning was the first morning I had any hint of ammonia, I was wondering if I kicked it off with the Nutrifin Cycle stuff. So now I have only 2 barbs and one of them looks a little bad, the nipper is chasing him all over.
Again sorry for all that, I know its a lot to read.
So the question is where to go from here. My plan is too continue the prescribed NUTRIFIN Cycle process on the bottle and leave the two Barbs in and see if the survive. I am hoping my cycle will be right after a few days/weeks. Is this a practical way to go? How do I tell the cycle is complete? Any other advice? Part of me hope the other two die so I can get a less agressive fish.
THANKS SO MUCH
