ok here goes...i think my first problem was that i didnt do the big water change at the end, i figured that since my nitrates 5-10 i didnt need to, but i guess that was wrong. the only chemicals that i put into the tank are aqueon water conditioner and API algaefix. my heater is and was always set at 80, i also have a thermometer in the tank and it says that im at 80 degrees spot on. i always conduct the tests myself but i ask my wife and 3 daughters ages 17,12, 9 to help me read them, i always read it myself and ask them to confirm or deny what i see. yes the tank cycled right after memorial day and i continued to dose it up to 4ppm everyday. the last dosing was saturday at 1pm and by yesterday at 12pm it was back to zero. i waited about an hr, tested everything again and went to petsmart. i used ace brand ammonia, it passed the shake test and it was highly recommended by person after person allover the net so i went with that. i put the fish bag into the tag for as long as i could leave it in there before the cichlids started going after each other. they were nice and calm on the ride home but after about five mins of the bag being in the tank they sprung to life after fifteen mins or so i set them free into the tank but simply cutting the bag open..so yes i got the store water into my tank but i made sure to stand and watch the fish at the store before asking to purchase them and they were all active and healthy. so i figure the water was fine there. i have all cichlid substrate which is just small shells and texas holey rock for deco. i also purchased an ancient ruins deco from petsmart on saturday but made sure to rinse it thoroughly in the shower with warm water before adding it. yes the fish seemed to be going to the surface for air and coming back down after i put them into the tank. i figured that was from lack of oxygen so i ran to petco and got an airpump but it didnt help. I JUST CHANGED 2O GALLONS OF WATER AND THE AURATUS AND PLECO ARE UP AND RUNNING AROUND THE TANK AGAIN. THE JEWEL CICHLID IS STILL SITTING ON THE BOTTOM ALIVE BUT JUST SITTING THERE. the chemicals are as follows ph is reading 7.4 on the high range test and 7.6 on the normal ph test, so figure its between 7.4-7.6, ammonia is 0 the nitrite is 0 nitrate is 5-20 i cant tell the diff. i will test it again at 2 when my wife comes home from work.
