Hi to all, just a quick question in regards of using natural seawater for my reef aquarium. I have bought this seawater from my local aquarium for $0.05/g where they took from the sea and then they filter it. They have used this seawater for their own aquarium without any problems and have been selling this seawater for the past 5 years or so.
So my question is do I have to do the nitrogen cycle or it doesn't need to?
I have tested all paramaters such as Ph, Alk, Calc, Salidity, etc. And all of those are good.
