so i started a new saltwater tank75 gal hex for the first time 25 days ago, I used the fritz turbo 900 and Dr Tim's ammonia, I did exactly how the instructions said online, I let it go.... last week I started testing and my ammonia was still little high I have all Hanna digital test equipment, I am new too saltwater let me add, I was at like .09ppm my nitrites were high around 2.5-5.0 but my nitrates are at 0 have been at zero Evey night, so last week I read to add some prime I added prime my nitrites were maybe a tad lower but not much so I let it sit a week, I tested it yesterday was still high so I did a 30 percent water change that helped I am down to .5 on my nitrite and .01ppm on my ammonia and 0 on nitrate my ph. is 8.1 and my salinity is 35.8 , I did add some ceopodes last week, I added like 4 jars its driving me crazy because I think I may have killed them I don't see any movement at night with lights off i do have 50 lbs. of rock in my tank so they possible can be hiding way inside the rock, My rock wasn't live it was dry when I started it, I added 1.5 bags of live sand, hoping that would kick it off ,I am just in thought on this, any help or pointers would be greatly appreciated do I just leave it and add more fritz turbo 900 to be safe??? I just turned the light on in the tank last night!!!!
