It is indeed closest to that blue. I tested it twice and it was the same colour. I think its blue just not as bright as 0.
So just to confirm, if my nitrite is 0 tonight, that means 3ppm has processed within 24 hours, so I should add 5ppm ammonia and then my cycle is over once it all cycles within 12 hours(if its quicker than that still do it for 7 days?) Or is it I cycle it all within 12 hours and then once its doing that, continue it for a week?

I like the idea of varied plants too just with low tech approach. Fish could still sift through the sand without disturbing the substrate? Or is that a disadvantage of the extra substrate below the sand?
block it in with stone so it doesn't fall everywhere.
