Thanks. I set up aquarium for about two weeks then gradually started adding fish every 2-3 weeks. I will get Easy Green too, and take some water to local aquarium shop for testing and comparison with my strips.

GH same at tap and aquarium 25 mg/ml, low range of OK on my strip KH again same at tap and aquarium, 40 mg/ml, low range of OK on my strip pH is 6.4 from tap, slightly darker but still closest to 6.4 in aquarium Yes have plant tabs and dose once weekly with liquid API Leaf zone but which is potash 3.00% and iron 0.10%

I have 3 month old 37 gal tank, planted with some java fern, anubias, amazon sword. Have been doing 20% water change weekly. Fish are doing well (2 corys, 4 algae eaters Otos, 5 black neon, 2 honey gourami). Ammonia, nitrite AND nitrate levels have always been zero. pH 6.4, soft water. Plants : java fern producing lots of offshoots (not sure of proper term) at tips of leaves, anubias and swords look ok but not really growing much. Should I be concerned that nitrate levels are zero? Do I need for them to be higher? And advice on achieving that. Thanks, newbie here
