Sorry, should've been more specific. Already dosing co2
, trace, iron, potassium. I've just never had a tank that didn't hang out around 10ppm nitrates so dosing nitrates didn't occur to me until recently.
There are more fish to be added soon as I get the money together to order them in, but I'm thinking more neons, corys, and hatchetfish aren't going to be enough to spike the bio load in the numbers I'm planning.
I'm using thrive for the low light goldfish tank. I may look into it for this one too.
