Thanks all, I'll sleep better tonight knowing it wasn't as catastrophic as I thought it might have been. Water test showed that the parameters were unchanged since last tested. I added my first critters today.

Let the fish gazing begin!

And thanks again for the advice.

Too much worrying is why people spend sleepless nights and too much money than they need to in this hobby IMO.
