Hi I have well established fish only tank. I have probably way to many fish in my tank and will out grow it pretty Quickly I'm aware of that and will be upgrading in the future my tank is a 55g with a 20g L custome sump with over 130 lb of live rock I have all small/baby fish snow flake, firmented , black edge moray also 1 dragon wrass 1 baby shark 3 engineer gobies 1 panther grouper and 1 6 inch puffer. Also i have a 29 gallon that is a reef . My main question is I checked both the nitates and both read 160ppm I'm very confused and and that's the truth my fish should be died . Do u think my test kit is bad expires 2017 I do exactly as the instructions say
