New build - straight to nitrate reading

[ezbandrea]

Hi all,
I have a 57g freshwater new build which i have been running for 12 days now. i seeded it with filter pads from my smaller 10g tank.
I left it running for a couple of days with a few pinched of fish food, then added 7 Ember tetras after 3 days.
Initially Ammonia 0 Nitrite 0 Nirate 0.
I then added another 10 Embers and 2 Pygmy Corys.
I now have had reading for the last 3 days as Ammonia 0 Nitrite 0 Nitrate 5/10ppm.
Today i tested again and Nitrate has definately climbed to 10ppm.
I am new to all this ..... would i be alright adding my fish that are left in my smaller tank - 7 Cardinals, 3 Pencilfish and L134 Leopard Frog Pleco, and at the same time putting the remaining filter media in the new larger tank?

Since your ammonia and nitrite is 0 I'd say it's OK to add the rest of the fish and the filter media. Just keep an eye on levels and make sure there aren't any spikes. Does your tap water have nitrate?
