That sounds like a good start. Testing is the only way to actually KNOW it's cycled. There is no exact timeframe for when to add fish or corals. On the advice of some very helpful and patient folks in my local reef club, I did the following and couldn't be happier with the results thus far.
Cycled the tank with LR
& a raw shrimp.
It cycled quickly (very good cured LR
) in about 2 weeks.
I waited until about the 5 week point and added snails.
I waited another 3 weeks (2 month point) and added my first shrimp and fish.
It may not be for everyone and there's always more than one way to succeed, but nothing has died and the corals are rocking so I'm now a firm believer in going slow.
