cycle question-no algae's

[lovetoclown]

New to the hobby and don't want to add anything to the tank till its good and ready. I put 60 pounds of dry rock in a brute can with two power heads and a heater. Added a shrimp and some bio-spira and let marinate for over 5 weeks. Then a couple weeks ago added the 60 pounds of rock and 50 pounds of ocean direct sand and bio spira to the DT and started up the 2 power heads, heater, return pump and 20 gallon sump. Tested ammonia, nitrites, nitrates, alkalinity and so on and all seem in line. I am also ghost feeding the tank as well and still all is well, and I just started the skimmer up a couple days ago to break it in.
My question is how can I be sure the tank is ready for life? I have not had any diatoms or any other algae this far. Thanks.

You've got your cycle done, you can start slowly adding in fish now.

if your ammonia nitrates and nitrates are in line then you are a go for launch

If you want to be sure add a 1/4 teaspoon of pure ammonia to the tank and test. The ammonia should be neutralized into nitrates within 24 hours if the tank is cycled.

Ace hardware has it. Make sure its Pure ammonia, with no detergents.

It's called "Ace Hardware Janitorial Strength Ammonia"

Dollar Tree also sells pure ammonia but it is much weaker than the Ace
