What are they at now?
That's frustrating. Welcome to cycling [emoji23], it's a pain but totally worth it. Test in a few days and see what it says.
So the waiting did pay off. Thanks to all those that kept saying be patient. My Nitrites are at .50 so dropped pretty fast over night. I'll wait until they are zero before testing nitrates. So once i detect nitrates and if they seem to be over 20ppm i would just do a water change to bring them between 0-20ppm right?
Should i test the tank by putting in food or ammonia to see if it converts ammonia to nitrite to nitrates?
also would i have to ghost feed the tank until im ready to add fish?
Yes.
No.
No.
You should prepare for the incoming algae storm, and be ready to start adding your clean up crew once you lower your nitrates to reasonable levels.
Once the clean up crew starts eating the algae that has grown from your cycle, they will be releasing it back as ammonia again, and the cycle continues. You'll want to be switching to regular interval water changes now, whatever your preferred interval is (10% per week, 20% per two weeks, 20% per month, etc). That will lower nitrates over time.
A good way to think about the cycle, and your aquarium in general, is that it's all a closed box. What goes in (ammonia to start the cycle, fish food, etc) must come out (as fish growth/mass, coral growth/mass, algae growth/mass, or if it is dissolved in the water column as nitrates it comes out in water changes).
Take your time, slow down, don't second guess. Good things happen slowly, bad things happen quickly.
Should I expect an "algae storm" even if I'm using a gfo reactor? I've been running it for 22 days since the cycle began and just today it looks like it's finally cycled. I haven't seen any algae growth yet. I'm only using dry rock and haven't turned my lights on at all. Kept the tank away from any lights. My understanding is I won't see any brown algae grow for a couple more weeks, months. Please correct me if I'm wrong.
After I bring my nitrates down as they seem pretty high 40-80ppm depending on which test kit I'm using, should I introduce 1-2 fish and a cuc, not one for algae since I don't have any but for dealing with fish food, poop etc ?
