OKay we'll first thing first  Nice to see someone from Rimbey i was raised there as we'll
Okay so did you add the rock and cycle the tank with the rock in it? Or how did you cycle it before you added the fish?
The idea of cycling is sand,water,rock and then wait for the cycle. Depending on where you get the rock from that could be a week to over month to cycle.
The fact that you are getting good readings is a good thing. But i guess like Myka said what are the actual numbers?
The cyano could be due to not enough flow. And in a biocube unless you have added more flow that will contribute to that problem.
What is the temp getting to in that tank?
Great board to get involved with lots of help here.
But Myka is right Sloooooow down. This is not a hobby for impatience
