Some notes about setup:
I usually don't test that much other than PH for co2 levels, but ran some numbers the other day. NO3 was definitely on the high end. This is attributable to normal EI dosing and limited plant mass.
PH - Tap 7.6, Co2 enriched 6.6-6.8
KH - Tap 2, Tank 7 (due to Seiryu Stone)
No3 - Before water change 70 - 100ppm, After water change 40-50ppm
Please note, these high nitrate numbers are from dosing dry salts and not from organic decomposition. This tank receives 1-2 50% weekly water changes to keep organics low and KH reasonable due to Seiryu Stones.
There are no sensitive stems in this setup so even with the high KH I'm not having any problems, but more notably there is no algae (even with limited plant mass) and the fish, shrimp and snails are all doing great. I've lost one critter (a golden back yellow shrimp) day after I bought it since I started this tank. No jumpers either with a 1" space between top of tank and water level. Tank is on a 15 hr light period including dim ramp up/ramp down and a 3 hr max burst.
I never "formally" cycled this tank by adding ammonia or fish right away. I simply waited around 4 weeks and slowly added fish each week after that. The system took care of the rest.
