Hey Alex, tank is looking great! get that co2 up and running, and those plants will take off.
Subscribed, looking forward to seeing how this turns out.
The only way to know when a tank is done cycling is to pick up a test kit. You want 0 ammonia, and 0 nitrites. Nitrates are fine, they aren't nearly as toxic as the nitrites or ammonia. as soon as you zero out nitrites and ammonia you should be good to go for livestock.
