WAIT. Take a breathe.
Lets get someone to take a look at the tank.
I can make it tomorrow or during the daytime is best, but if you can not get someone out there before SOON, call me, and I will drive down tonight.
We need to get some good test results and dtermine which scale you are on for the nitrates.
Dont bother with testing of nitirites anymore, (unless you get a very large algae outbreak)
You need to do a 50% water change like right now!!!
What are your stats, tank size, age, occupants, corals etc...
Age, I think maybe a factor here, but that is a very early / preliminary diagnosis.
We will figure out exactly what the problems are. But water changes are in your future right now.
Do you have RO/DI filter? Do you hve mixing barrels.
If not, how many 5 gallon buckets do you have, and can you get more, or get access to 55 gall barrel to mix salt water in.
If you have a mixing barrel, mix up as much salt water as it can hold, no lights, circ pump and or air pump, and let sit for as long as possible.
Unfortunately, I only have a one five gallon bucket, to bring with me, but hopefully you will have plenty on hand
Call me to make arrangements for me to come down.
