Hi Tanz - basically: yes. BUT, I would wait until you have had those water parameters for at least 2 to 3 weeks, before adding the 1st fish. And when you DO add fish, you should think carefully of what fish you want to add.
Think of what type of tank you want to keep. And also think/ask about fish compatibility. Not all marine fish can be kept together - as some fish might fight and kill each other, while others might just not eat or get enough food from a new tank - and wither away and die.....
There are some hardy fish that end up becoming terrorists in our tanks - so, these might also be a no-no to add.....
So - when you ready - ask away.....
