High nitrite and nitrate early in fishless cycle - problem?
I planted and filled my new 10 g tank on Saturday (first tank). The tank has ADA Amazonia and Power Sand. 3 Fluorish root tabs and 3 Osmocote plus capsules at the base of the substrate (placed before adding water). The tank is pretty heavily planted to start - with a mix of crypts, hygrophila and anubias with floaters (Red root floaters and salvinia).
Water out of the tap (Tested with brand new API freshwater master test kit; expiration 2017):
Treated water with Prime and added to tank. Also treated tank with Seachem Stability (5 ml Day 1, 2.5 mls each day since) and Excel (1 ml once daily).
On day 2 the water readings were as follows:
Day 3 - I just checked ammonia - 4
Day 5 (today)
I know that the Aquasoil will leach ammonia, but why do I have nitrite and nitrates already? Should I be worried that the fluorish root tabs and or osmocote is leaching? The plants all seem to be doing very well, with the exception of some crypt melt that occurred when the plants shipped. Still losing a few leaves here and there - but seeing new growth on almost all - and I have already had to trim a couple of rotala stems that hit the top of the water.
I have topped water off a couple of times (lidless, slow evaporation) - but haven't tried a water change. What should I do? Do I need to do anything?
