Did the full battery of tests tonight:
Ammonia: 0+ (just the tiniest bit greener than yellow. Not nearly so green as the .25 ppm strip - the first one after 0)
Nitrite: 0+ (again, just a hair darker than the 0, much lighter than the .25)
Nitrate: Could be 40, could be 80 - to my eye, the test strip is identical.
pH: 7.4 (need to chuck a little peat in the filter)
It's only been running a week, but the biowheel on the Penguin 3 is from an established tank (it spent the night in a ziploc of aquarium water, but it was running the next day), and some of the bottom layer of gravel is also from an established tank. I think this might could be cycled.
I'll test it again tomorrow, and if I get the same readings, I'm going to pop the striatas and the yoyo over.
Added some more Bacopa to the right side. Starting to get some balance.
