Lights come on at 9am and go off at about 9pm. There's lots of plants in there and they are growing, visibly. They all seem pretty happy.
The water looks a little gold to me, more than green. I have had algae blooms in the 5 gallon before, when things went out of kilter, and this doesn't look like that. It's more brownish gold. Not sure it's not the bogwood making blackwater. But it could be algae.
There is no fertilizer in the substrate, so I put in slightly less than what the Tropica plant food dose was, for the tank. That was literally the same day the plants went in. I haven't added anything since.
I'm a bit confused as to how I've got such a high level of nitrites - seriously, it was like six grains of sinking pellets (Tetra Pro Color) in the 60 litre tank.
I was really hoping I could get some of the smaller corys in there to get them more room, as the nursery net is getting a bit crowded as they grow. I'm thinking that's probably a pretty good way to kill them, though, at present.
I had considered draining it by several litres and replacing with fresh, treated water. But that would that delay the cycle getting to the point that it would be safe to put the corys in, wouldn't it?
I had made arrangements to have the guy at the fish store test the water tomorrow, so perhaps he will be able to tell me more. I have already ordered the more accurate testing kit, but it won't be in for a few days.
